CVE-2018-15856 2 Canonical, Xkbcommon 2 Ubuntu Linux, Xkbcommon 2024-11-21 2.1 LOW 5.5 MEDIUM
An infinite loop when reaching EOL unexpectedly in compose/parser.c (aka the keymap parser) in xkbcommon before 0.8.1 could be used by local attackers to cause a denial of service during parsing of crafted keymap files.
CVE-2018-15855 2 Canonical, Xkbcommon Project 2 Ubuntu Linux, Xkbcommon 2024-11-21 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage in xkbcommon before 0.8.1 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because the XkbFile for an xkb_geometry section was mishandled.
CVE-2018-15854 2 Canonical, Xkbcommon Project 2 Ubuntu Linux, Xkbcommon 2024-11-21 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage in xkbcommon before 0.8.1 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because geometry tokens were desupported incorrectly.
CVE-2018-15853 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2024-11-21 2.1 LOW 5.5 MEDIUM
Endless recursion exists in xkbcomp/expr.c in xkbcommon and libxkbcommon before 0.8.1, which could be used by local attackers to crash xkbcommon users by supplying a crafted keymap file that triggers boolean negation.
CVE-2018-15822 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2024-11-21 5.0 MEDIUM 7.5 HIGH
The flv_write_packet function in libavformat/flvenc.c in FFmpeg through 2.8 does not check for an empty audio packet, leading to an assertion failure.
CVE-2018-15594 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 2.1 LOW 5.5 MEDIUM
arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests.
CVE-2018-15572 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 2.1 LOW 6.5 MEDIUM
The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c in the Linux kernel before 4.18.1 does not always fill RSB upon a context switch, which makes it easier for attackers to conduct userspace-userspace spectreRSB attacks.
CVE-2018-15473 7 Canonical, Debian, Netapp and 4 more 24 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 21 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.
CVE-2018-15471 3 Canonical, Linux, Xen 3 Ubuntu Linux, Linux Kernel, Xen 2024-11-21 6.8 MEDIUM 7.8 HIGH
An issue was discovered in xenvif_set_hash_mapping in drivers/net/xen-netback/hash.c in the Linux kernel through 4.18.1, as used in Xen through 4.11.x and other products. The Linux netback driver allows frontends to control mapping of requests to request queues. When processing a request to set or change this mapping, some input validation (e.g., for an integer overflow) was missing or flawed, leading to OOB access in hash handling. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in one or more of privilege escalation, Denial of Service (DoS), or information leaks.
CVE-2018-15378 3 Canonical, Clamav, Debian 3 Ubuntu Linux, Clamav, Debian Linux 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A vulnerability in ClamAV versions prior to 0.100.2 could allow an attacker to cause a denial of service (DoS) condition. The vulnerability is due to an error related to the MEW unpacker within the "unmew11()" function (libclamav/mew.c), which can be exploited to trigger an invalid read memory access via a specially crafted EXE file.
CVE-2018-15127 4 Canonical, Debian, Libvnc Project and 1 more 9 Ubuntu Linux, Debian Linux, Libvncserver and 6 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
LibVNC before commit 502821828ed00b4a2c4bef90683d0fd88ce495de contains heap out-of-bound write vulnerability in server code of file transfer extension that can result remote code execution
CVE-2018-15126 3 Canonical, Debian, Libvnc Project 3 Ubuntu Linux, Debian Linux, Libvncserver 2024-11-21 7.5 HIGH 9.8 CRITICAL
LibVNC before commit 73cb96fec028a576a5a24417b57723b55854ad7b contains heap use-after-free vulnerability in server code of file transfer extension that can result remote code execution
CVE-2018-15120 2 Canonical, Gnome 2 Ubuntu Linux, Pango 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
libpango in Pango 1.40.8 through 1.42.3, as used in hexchat and other products, allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted text with invalid Unicode sequences.
CVE-2018-14938 2 Canonical, Digitalcorpora 2 Ubuntu Linux, Tcpflow 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
An issue was discovered in wifipcap/wifipcap.cpp in TCPFLOW through 1.5.0-alpha. There is an integer overflow in the function handle_prism during caplen processing. If the caplen is less than 144, one can cause an integer overflow in the function handle_80211, which will result in an out-of-bounds read and may allow access to sensitive memory (or a denial of service).
CVE-2018-14883 4 Canonical, Debian, Netapp and 1 more 4 Ubuntu Linux, Debian Linux, Storage Automation Store and 1 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in PHP before 5.6.37, 7.0.x before 7.0.31, 7.1.x before 7.1.20, and 7.2.x before 7.2.8. An Integer Overflow leads to a heap-based buffer over-read in exif_thumbnail_extract of exif.c.
CVE-2018-14851 4 Canonical, Debian, Netapp and 1 more 4 Ubuntu Linux, Debian Linux, Storage Automation Store and 1 more 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
exif_process_IFD_in_MAKERNOTE in ext/exif/exif.c in PHP before 5.6.37, 7.0.x before 7.0.31, 7.1.x before 7.1.20, and 7.2.x before 7.2.8 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted JPEG file.
CVE-2018-14734 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 6.1 MEDIUM 7.8 HIGH
drivers/infiniband/core/ucma.c in the Linux kernel through 4.17.11 allows ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allows attackers to cause a denial of service (use-after-free).
CVE-2018-14682 5 Cabextract, Cabextract Project, Canonical and 2 more 8 Libmspack, Cabextract, Ubuntu Linux and 5 more 2024-11-21 6.8 MEDIUM 8.8 HIGH

An issue was discovered in kwajd_read_headers in mspack/kwajd.c in libmspack before 0.7alpha. Bad KWAJ file header extensions could cause a one or two byte overwrite.
