CVSS v3.1 |
| Microsoft Office 2007 SP2, Microsoft Office Word Viewer, Microsoft Office 2010 SP2, Microsoft Office 2013 SP1 and RT SP1, Microsoft Office 2016, and Microsoft Office 2016 Click-to-Run (C2R) allow a remote code execution vulnerability, due to how Office handles objects in memory, aka "Microsoft Office Memory Corruption Vulnerability". This CVE is unique from CVE-2018-0852. |
| A buffer overflow vulnerability in HPE NonStop RDMA SERVICES NSK may cause out-of-bounds memory write, which may result in memory corruption. |
| Out-of-bounds write vulnerability in Citrix Workspace app for Windows.
This issue affects Workspace app for Windows: before 2603.20 CR, before LTSR 2607 Hotfix 1, and before LTSR 2507 CU3 Hotfix 1. |
| A flaw was found in Ghostscript. When Ghostscript renders a crafted PostScript or EPS document, it can bypass the -dSAFER sandbox and execute arbitrary shell commands in the context of the Ghostscript process. The issue chains memory corruption in document parsing with disabling of internal path access controls at runtime. An attacker can deliver the document directly or through formats that delegate rendering to Ghostscript (for example EPS import or print conversion workflows). Successful exploitation can compromise confidentiality, integrity, and availability of data accessible to the process running Ghostscript. |
| A flaw was found in DPDK lib/vhost vhost-crypto. Integer overflow in chain length checks, and missing length checks on the RSA path, can overflow a host buffer in the vhost-crypto backend. |
| A flaw was found in DPDK lib/vhost vhost-crypto. A guest can supply an avail-ring descriptor index that is used without bounds checking, causing an out-of-bounds write in the host vhost-crypto backend. |
| A flaw was found in DPDK lib/vhost. A guest can desynchronize virtqueue size from inflight descriptor table size, causing an out-of-bounds write in the host vhost process. |
| FreeRDP 3.3.0 before 3.32.0, when built with WINPR_UTILS_IMAGE_JPEG=ON, has a heap-based out-of-bounds write in winpr_convert_from_jpeg because grayscale JPEG buffers are sized from one input component rather than three BGR output components. A malicious RDP server can offer a grayscale JPEG via clipboard redirection, corrupting client memory and crashing it when the item is pasted as CF_DIB bitmap data. |
| A vulnerability has been found in GPAC up to 26.07.0. This vulnerability affects the function gf_m2ts_decode_ait of the file src/media_tools/ait.c of the component AIT Parser. Such manipulation leads to out-of-bounds write. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The name of the patch is 6d2c21a1a688abb20d0111b608db3b6f44d348f4. Applying a patch is advised to resolve this issue. |
| A heap-based out-of-bounds write in the ws_read_frame function (src/bolt/ws.c) and the buffer_apply_mask function (src/bolt/buffer.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to cause a denial of service and possibly corrupt heap memory by sending a WebSocket frame with a 64-bit extended payload length to the Bolt port. The payload length is not bounded, and the only bounds check in buffer_apply_mask is an ASSERT(), which is compiled out in release builds, so the function XORs memory beyond the end of the receive buffer with the attacker-supplied mask key. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected. |
| A heap-based out-of-bounds write in the BoltReadHandler function (src/bolt/bolt_api.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to cause a denial of service and possibly execute arbitrary code by sending a Bolt RESET message with an attacker-chosen chunk size to the Bolt port. The handler checks the size only with ASSERT(), which is compiled out in release builds, then computes a destination pointer from the wire-supplied 16-bit size and moves buffered data up to about 64 KiB backwards past the start of the read buffer. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected. |
| A flaw was found in the GStreamer multimedia framework's ASF muxer plugin (asfmux). When writing string metadata tags containing Unicode characters outside the Basic Multilingual Plane (such as emoji) to an ASF container, the plugin incorrectly calculates the buffer size needed for the UTF-16LE representation. The size calculation assumes each Unicode code point requires 2 bytes, but non-BMP characters require 4 bytes (surrogate pairs). This leads to a heap out-of-bounds write when the actual UTF-16LE conversion is written into the undersized buffer. An attacker could exploit this by providing media with crafted metadata tags to an application that transcodes or remuxes to ASF format while preserving metadata, potentially causing a denial of service or limited memory corruption. |
| Unspecified vulnerability in Oracle Java SE 6u105, 7u91, and 8u66; Java SE Embedded 8u65; and JRockit R28.3.8 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to AWT. NOTE: the previous information is from the January 2016 CPU. Oracle has not commented on third-party claims that this is a heap-based buffer overflow in the readImage function, which allows remote attackers to execute arbitrary code via crafted image data. |
| A vulnerability was identified in Artifex Ghostscript up to 10.07.0. Affected is the function type1_callsubr of the file devices/vector/gdevpsfx.c of the component Pdfwrite. The manipulation leads to stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. Upgrading to version 10.08.0 is able to address this issue. It is suggested to upgrade the affected component. A solution was implemented: "I've chosen to fix this slightly differently by using the defined macro in the font parsing loop rather than in the callsubr function, because this better matches the pattern of 'normal' usage." |
| A flaw was found in the DPDK nfp vDPA driver. Stack and heap buffers sized for a single queue pair can be overflowed when more virtqueues are configured, leading to a host crash or memory corruption. |
| A heap-based out-of-bounds write vulnerability exists in Foxit PDF Editor/Reader’s PRC parser due to insufficient validation of vertex indices in triangular fan texture meshes. Successful exploitation could result in memory corruption and an application crash. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: account for fraggap on the paged allocation path
In __ip6_append_data(), when the paged-allocation branch is taken
(MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are
computed as
alloclen = fragheaderlen + transhdrlen;
pagedlen = datalen - transhdrlen;
datalen already includes fraggap (datalen = length + fraggap). When
fraggap is non-zero, this is not the first skb and transhdrlen is zero.
The fraggap bytes carried over from the previous skb are copied just past
the fragment headers in the new skb's linear area. The linear area is
therefore undersized by fraggap bytes while pagedlen is overstated by the
same amount, and the copy writes past skb->end into the trailing
skb_shared_info.
An unprivileged user can trigger this via a UDPv6 socket using
MSG_MORE together with MSG_SPLICE_PAGES.
The bad accounting was introduced by commit 773ba4fe9104 ("ipv6:
avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix
__ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative
copy value caused -EINVAL to be returned. That later commit allowed
MSG_SPLICE_PAGES to proceed in this case, making the corruption
triggerable.
The non-paged branch sets alloclen to fraglen, which already accounts
for fraggap because datalen does. Bring the paged branch in line by
adding fraggap to alloclen and subtracting it from pagedlen.
After this adjustment, copy no longer collapses to -fraggap on the
paged path, so remove the stale comment describing that old arithmetic.
Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES
case, remove the MSG_SPLICE_PAGES exception from the negative copy check. |

ring-buffer: Add checking nr_subbufs to persistent ring buffer validation
Sashiko reported that the code was using meta->nr_subbufs without making
sure that it matched the nr_pages + 1 on data that was assuming the two
were the same.
Add a check to the persistent ring buffer validation code to make sure
that the saved nr_subbufs matches what we expect. |

uprobes/x86: Move optimized uprobe from nop5 to nop10
Andrii reported an issue with optimized uprobes [1] that can clobber
redzone area with call instruction storing return address on stack
where user code may keep temporary data without adjusting rsp.
Fixing this by moving the optimized uprobes on top of 10-bytes nop
instruction, so we can squeeze another instruction to escape the
redzone area before doing the call, like:
lea -0x80(%rsp), %rsp
call tramp
Note the lea instruction is used to adjust the rsp register without
changing the flags.
We use nop10 and following transformation to optimized instructions
above and back as suggested by Peterz [2].
Optimize path (int3_update_optimize):
1) Initial state after set_swbp() installed the uprobe:
cc 2e 0f 1f 84 00 00 00 00 00
From offset 0 this is INT3 followed by the tail of the original
10-byte NOP.
After a previous unoptimization bytes 5..9 may still contain the
old call instruction, which remains valid for threads already there.
2) Rewrite the LEA tail and call displacement:
cc [8d 64 24 80 e8 d0 d1 d2 d3]
From offset 0 this traps on the uprobe INT3. Bytes 1..9 are not
executable entry points while byte 0 is trapped.
3) Publish the first LEA byte:
[48] 8d 64 24 80 e8 d0 d1 d2 d3
From offset 0 this is:
lea -0x80(%rsp), %rsp
call <uprobe-trampoline>
Unoptimize path (int3_update_unoptimize):
1) Initial optimized state:
48 8d 64 24 80 e8 d0 d1 d2 d3
Same as 3) above.
2) Trap new entries before restoring the NOP bytes:
[cc] 8d 64 24 80 e8 d0 d1 d2 d3
From offset 0 this traps. A thread that had already executed the
LEA can still reach the intact CALL at offset 5.
3) Restore bytes 1..4 of the original NOP while keeping byte 0 trapped
and byte 5 as CALL.
cc [2e 0f 1f 84] e8 d0 d1 d2 d3
From offset 0 this still traps. Offset 5 is still the CALL for any
thread that was already past the first LEA byte.
4) Publish the first byte of the original NOP:
[66] 2e 0f 1f 84 e8 d0 d1 d2 d3
From offset 0 this is the restored 10-byte NOP; the CALL opcode and
displacement are now only NOP operands. Offset 5 still decodes as
CALL for a thread that was already there.
Tthere is only a single target uprobe-trampoline for the given nop10
instruction address, so the CALL instruction will not be changed across
unoptimization/optimization cycles.
Therefore, any task that is preempted at the CALL instruction is guaranteed
to observe that CALL and not anything else.
Note as explained in [2] we need to use following nop10:
PF1 PF2 ESC NOPL MOD SIB DISP32
NOP10: 0x66, 0x2e, 0x0f, 0x1f, 0x84, 0x00, 0x00, 0x00, 0x00, 0x00 -- cs nopw 0x00000000(%rax,%rax,1)
which means we need to allow 0x2e prefix which maps to INAT_PFX_CS
attribute in is_prefix_bad function.
Also changing the uprobe syscall error when called out of uprobe
trampoline to -EPROTO, so we are able to detect the fixed kernel.
The optimized uprobe performance stays the same:
uprobe-nop : 3.129 ± 0.013M/s
uprobe-push : 3.045 ± 0.006M/s
uprobe-ret : 1.095 ± 0.004M/s
--> uprobe-nop10 : 7.170 ± 0.020M/s
uretprobe-nop : 2.143 ± 0.021M/s
uretprobe-push : 2.090 ± 0.000M/s
uretprobe-ret : 0.942 ± 0.000M/s
--> uretprobe-nop10: 3.381 ± 0.003M/s
usdt-nop : 3.245 ± 0.004M/s
--> usdt-nop10 : 7.256 ± 0.023M/s

| In the Linux kernel, the following vulnerability has been resolved:
LoongArch: KVM: Validate MSI data before routing it to EIOINTC
pch_msi_set_irq() passes e->msi.data straight into eiointc_set_irq() as
the irq number. The MSI data comes from userspace, that either via a
KVM_IRQ_ROUTING_MSI entry set with KVM_SET_GSI_ROUTING (used by irqfd
and KVM_IRQ_LINE) or directly via KVM_SIGNAL_MSI, and is never checked
against EIOINTC_IRQS.
eiointc_set_irq() uses the value with __set_bit()/__clear_bit() on the
256-bit isr bitmap, eiointc_update_irq() then indexes sw_coremap[] and
the per-cpu coreisr/sw_coreisr bitmaps with it. Therefore a data value
>= 256 reads and writes memory past the end of those arrays, i.e. any
process holding a VM fd can corrupt kernel memory beyond the allocation
of loongarch_eiointc.
Reject MSI data that doesn't fit in the EIOINTC irq space. The DMSINTC
path is unaffected as it decodes the vector from the address and masks
it. |
