Bug 875518 (CVE-2022-42010, CVE-2022-42011, CVE-2022-42012) – <sys-apps/dbus-1.14.4: Multiple vulnerabilities

• Product: Gentoo Security
• Status: IN_PROGRESS ---

[Description Sam James 2022-10-05 19:07:50 UTC]

From 1.14.4 release notes (https://lists.freedesktop.org/archives/ftp-release/2022-October/000777.html):

Denial of service fixes:

Evgeny Vereshchagin discovered several ways in which an authenticated
local attacker could cause a crash (denial of service) in
dbus-daemon --system or a custom DBusServer. In uncommon configurations
these could potentially be carried out by an authenticated remote attacker.

• An invalid array of fixed-length elements where the length of the array
 is not a multiple of the length of the element would cause an assertion
 failure in debug builds or an out-of-bounds read in production builds.
 This was a regression in version 1.3.0.
 (dbus#413, CVE-2022-42011; Simon McVittie)

• A syntactically invalid type signature with incorrectly nested parentheses
 and curly brackets would cause an assertion failure in debug builds.
 Similar messages could potentially result in a crash or incorrect message
 processing in a production build, although we are not aware of a practical
 example. (dbus#418, CVE-2022-42010; Simon McVittie)

• A message in non-native endianness with out-of-band Unix file descriptors
 would cause a use-after-free and possible memory corruption in production
 builds, or an assertion failure in debug builds. This was a regression in
 version 1.3.0. (dbus#417, CVE-2022-42012; Simon McVittie)
