Slackware Linux 15.0 / current util-linux Vulnerability (SSA:2022-046-02)

medium Nessus Plugin ID 158105

Language:

Synopsis

The remote Slackware Linux host is missing a security update to util-linux.

Description

The version of util-linux installed on the remote host is prior to 2.37.4. It is, therefore, affected by a vulnerability as referenced in the SSA:2022-046-02 advisory.

 - A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an INPUTRC environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation.
 This flaw affects util-linux versions prior to 2.37.4. (CVE-2022-0563)

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 util-linux package.
