MGASA-2022-0028 - Updated glibc packages fix security vulnerabilities

Publication date: 23 Jan 2022
URL: https://advisories.mageia.org/MGASA-2022-0028.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-23218,
     CVE-2022-23219

Description:
Updated glibc packages fix security vulnerabilities:

The deprecated compatibility function svcunix_create in the sunrpc module
of the GNU C Library (aka glibc) through 2.34 copies its path argument on
the stack without validating its length, which may result in a buffer
overflow, potentially resulting in a denial of service or (if an application
is not built with a stack protector enabled) arbitrary code execution
(CVE-2022-23218).

The deprecated compatibility function clnt_create in the sunrpc module of
the GNU C Library (aka glibc) through 2.34 copies its hostname argument on
the stack without validating its length, which may result in a buffer
overflow, potentially resulting in a denial of service or (if an
application is not built with a stack protector enabled) arbitrary code
execution (CVE-2022-23219).
