-------------------------------------------------------------------------

Package : util-linux Version : 2.33.1-0.1+deb10u1 CVE ID : CVE-2021-37600 CVE-2024-28085 Debian Bug : 826596 991619 1067849

CVE-2024-28085

Skyler Ferrante discovered that the wall(1) utility found in util-linux, a collection of system utilities for Linux, does not filter escape sequences from command line arguments. This allows unprivileged local users to put arbitrary text on other users terminals if mesg is set to y and the wall executable is setgid, which could lead to information disclosure.

With this update the wall executable is no longer installed setgid tty.

CVE-2021-37600

Kihong Heo found an integer overflow which can potentially lead to buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file.
NOTE: this is issue is unexploitable in GNU C Library environments, and possibly in all realistic environments.

For Debian 10 buster, these problems have been fixed in version 2.33.1-0.1+deb10u1.

We recommend that you upgrade your util-linux packages.
