Affected Mageia releases: 8
CVE: CVE-2022-42010,
     CVE-2022-42011,
     CVE-2022-42012

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. (CVE-2022-42010)

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.
(CVE-2022-42011)

A message in non-native endianness with out-of-band Unix file descriptorswould cause a use-after-free and possible memory corruption in production
builds, or an assertion failure in debug builds. (CVE-2022-42012)
