Slackware Linux 14.0 / 14.1 / 14.2 / 15.0 / current sudo Vulnerability (SSA:2022-309-01)

high Nessus Plugin ID 167045

Language:

Synopsis

The remote Slackware Linux host is missing a security update to sudo.

Description

The version of sudo installed on the remote host is prior to 1.9.12p1. It is, therefore, affected by a vulnerability as referenced in the SSA:2022-309-01 advisory.

 - Sudo 1.8.0 through 1.9.12, with the crypt() password backend, contains a plugins/sudoers/auth/passwd.c array-out-of-bounds error that can result in a heap-based buffer over-read. This can be triggered by arbitrary local users with access to Sudo by entering a password of seven characters or fewer. The impact could vary depending on the system libraries, compiler, and processor architecture. (CVE-2022-43995)

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

Solution

Upgrade the affected sudo package.
