Unchecked NULL pointer usage when parsing invalid atoms in ExprResolveLhs in xkbcomp/expr.c in xkbcommon before 0.8.2 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because lookup failures are mishandled.
CVE-2018-15858 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2024-11-21 2.1 LOW 5.5 MEDIUM
Unchecked NULL pointer usage when handling invalid aliases in CopyKeyAliasesToKeymap in xkbcomp/keycodes.c 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.
CVE-2018-15857 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2024-11-21 4.6 MEDIUM 7.8 HIGH
An invalid free in ExprAppendMultiKeysymList in xkbcomp/ast-build.c in xkbcommon before 0.8.1 could be used by local attackers to crash xkbcommon keymap parsers or possibly have unspecified other impact by supplying a crafted keymap file.
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.

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-2018-15471 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.
