Description Thomas Backlund 2022-01-22 20:21:25 CET

Security fixes:

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).

x86_64, Mate
Updated the eight packages via qarepo/MageiaUpdate and rebooted smoothly.
$ rpm -qa | grep glibc
glibc-static-devel-2.32-23.mga8
glibc-profile-2.32-23.mga8
glibc-2.32-23.mga8
glibc-utils-2.32-23.mga8
glibc-i18ndata-2.32-23.mga8
glibc-doc-2.32-23.mga8
glibc-devel-2.32-23.mga8
$ rpm -q nscd
nscd-2.32-23.mga8

Everything looks fine.  Nothing suspicious in dmesg.  Giving this an OK.

Comment 2 Thomas Andrews 2022-01-22 22:25:20 CET

(First validation was a slip of the mouse...)

Since this is so fundamental, also tested on real 32-bit hardware: Foolishness, my Dell Inspiron 5100, 32-bit P4, Xfce system.

Updated via qarepo, and rebooted. Everything looks good here, too. Giving it a 32-bit OK and validating.
