CVSS v3.1 |
| c-ares is an asynchronous resolver library. From 1.32.3 through 1.34.4, there is a use-after-free in read_answers() when process_answer() may re-enqueue a query either due to a DNS Cookie Failure or when the upstream server does not properly support EDNS, or possibly on TCP queries if the remote closed the connection immediately after a response. If there was an issue trying to put that new transaction on the wire, it would close the connection handle, but read_answers() was still expecting the connection handle to be available to possibly dequeue other responses. In theory a remote attacker might be able to trigger this by flooding the target with ICMP UNREACHABLE packets if they also control the upstream nameserver and can return a result with one of those conditions, this has been untested. Otherwise only a local attacker might be able to change system behavior to make send()/write() return a failure condition. This vulnerability is fixed in 1.34.5. |
| Use After Free vulnerability exists in the IPT file reading procedure in SOLIDWORKS eDrawings on Release SOLIDWORKS Desktop 2025. This vulnerability could allow an attacker to execute arbitrary code while opening a specially crafted IPT file. |
| It is possible to cause an use-after-free write in SANM decoding with a carefully crafted animation using subversion <2.
When a STOR chunk is present, a subsequent FOBJ chunk will be saved in ctx->stored_frame. Stored frames can later be referenced by FTCH chunks. For files using subversion < 2, the undecoded frame is stored, and decoded again when the FTCH chunks are parsed. However, in process_frame_obj if the frame has an invalid size, there’s an early return, with a value of 0.
This causes the code in decode_frame to still store the raw frame buffer into ctx->stored_frame. Leaving ctx->has_dimensions set to false.
A subsequent chunk with type FTCH would call process_ftch and decode that frame obj again, adding to the top/left values and calling process_frame_obj again.
Given that we never set ctx->have_dimensions before, this time we set the dimensions, calling init_buffers, which can reallocate the buffer in ctx->stored_frame, freeing the previous one. However, the GetByteContext object gb still holds a reference to the old buffer.
Finally, when the code tries to decode the frame, codecs that accept a GetByteContext as a parameter will trigger a use-after-free read when using gb.
GetByteContext is only used for reading bytes, so at most one could read invalid data. There are no heap allocations between the free and when the object is accessed. However, upon returning to process_ftch, the code restores the original values for top/left in stored_frame, writing 4 bytes to the freed data at offset 6, potentially corrupting the allocator’s metadata.
This issue can be triggered just by probing whether a file has the sanm format.
We recommend upgrading to version 8.0 or beyond. |
| A vulnerability was found in PX4 PX4-Autopilot up to 1.15.4. This issue affects the function MavlinkReceiver::handle_message_serial_control of the file src/modules/mavlink/mavlink_receiver.cpp of the component Mavlink Shell Closing Handler. The manipulation of the argument _mavlink_shell leads to use after free. An attack has to be approached locally. The complexity of an attack is rather high. The exploitation is known to be difficult. The identifier of the patch is 4395d4f00c49b888f030f5b43e2a779f1fa78708. It is recommended to apply a patch to fix this issue. |
| Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: mvsas: Fix use-after-free bugs in mvs_work_queue
During the detaching of Marvell's SAS/SATA controller, the original code
calls cancel_delayed_work() in mvs_free() to cancel the delayed work
item mwq->work_q. However, if mwq->work_q is already running, the
cancel_delayed_work() may fail to cancel it. This can lead to
use-after-free scenarios where mvs_free() frees the mvs_info while
mvs_work_queue() is still executing and attempts to access the
already-freed mvs_info.
A typical race condition is illustrated below:
CPU 0 (remove) | CPU 1 (delayed work callback)
mvs_pci_remove() |
mvs_free() | mvs_work_queue()
cancel_delayed_work() |
kfree(mvi) |
| mvi-> // UAF
Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure
that the delayed work item is properly canceled and any executing
delayed work item completes before the mvs_info is deallocated.
This bug was found by static analysis. |
| A vulnerability was determined in axboe fio up to 3.41. This impacts the function __parse_jobs_ini of the file init.c. Executing manipulation can lead to use after free. The attack needs to be launched locally. The exploit has been publicly disclosed and may be utilized. |
| Use After Free vulnerability exists in the CATPRODUCT file reading procedure in SOLIDWORKS eDrawings on Release SOLIDWORKS Desktop 2025. This vulnerability could allow an attacker to execute arbitrary code while opening a specially crafted CATPRODUCT file. |
| A Use After Free vulnerability affecting the PAR file reading procedure in SOLIDWORKS eDrawings on Release SOLIDWORKS Desktop 2025 could allow an attacker to execute arbitrary code while opening a specially crafted PAR file. |
| Use After Free vulnerability exists in the JT file reading procedure in SOLIDWORKS eDrawings on Release SOLIDWORKS Desktop 2025. This vulnerability could allow an attacker to execute arbitrary code while opening a specially crafted JT file. |
| pycares is a Python module which provides an interface to c-ares. c-ares is a C library that performs DNS requests and name resolutions asynchronously. Prior to version 4.9.0, pycares is vulnerable to a use-after-free condition that occurs when a Channel object is garbage collected while DNS queries are still pending. This results in a fatal Python error and interpreter crash. The vulnerability has been fixed in pycares 4.9.0 by implementing a safe channel destruction mechanism. |
| bt_sock_recvmsg in net/bluetooth/af_bluetooth.c in the Linux kernel through 6.6.8 has a use-after-free because of a bt_sock_ioctl race condition. |
| Open Robotics Robotic Operating System 2 (ROS2) and Nav2 humble version was discovered to contain a use-after-free in the nav2_amcl process. This vulnerability is triggered via sending a request to change dynamic parameters. |
| An unauthenticated local attacker may trick a user to open corrupted project files to crash the system due to use after free vulnerability. |
| Open Robotics Robotic Operating System 2 (ROS2) and Nav2 humble versions were discovered to contain a use-after-free via the nav2_amcl process. This vulnerability is triggerd via remotely sending a request for change the value of dynamic-parameter`/amcl max_beams` . |
| NVIDIA GPU display driver for Windows and Linux contains a vulnerability where referencing memory after it has been freed can lead to denial of service or data tampering. |
| Issue summary: Calling the OpenSSL API function SSL_free_buffers may cause
memory to be accessed that was previously freed in some situations
Impact summary: A use after free can have a range of potential consequences such
as the corruption of valid data, crashes or execution of arbitrary code.
However, only applications that directly call the SSL_free_buffers function are
affected by this issue. Applications that do not call this function are not
vulnerable. Our investigations indicate that this function is rarely used by
applications.
The SSL_free_buffers function is used to free the internal OpenSSL buffer used
when processing an incoming record from the network. The call is only expected
to succeed if the buffer is not currently in use. However, two scenarios have
been identified where the buffer is freed even when still in use.
The first scenario occurs where a record header has been received from the
network and processed by OpenSSL, but the full record body has not yet arrived.
In this case calling SSL_free_buffers will succeed even though a record has only
been partially processed and the buffer is still in use.
The second scenario occurs where a full record containing application data has
been received and processed by OpenSSL but the application has only read part of
this data. Again a call to SSL_free_buffers will succeed even though the buffer
is still in use.
While these scenarios could occur accidentally during normal operation a
malicious attacker could attempt to engineer a stituation where this occurs.
We are not aware of this issue being actively exploited.
The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. |
