GLSA-202401-29 : sudo: Memory Manipulation

high Nessus Plugin ID 189404

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202401-29 (sudo: Memory Manipulation)

 - Sudo before 1.9.15 might allow row hammer attacks (for authentication bypass or privilege escalation) because application logic sometimes is based on not equaling an error value (instead of equaling a success value), and because the values do not resist flips of a single bit. (CVE-2023-42465)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

All sudo users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=app-admin/sudo-1.9.15_p2
