Slackware Linux 15.0 / current less Vulnerability (SSA:2024-105-01)

high Nessus Plugin ID 193315

Language:

Synopsis

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

Description

The version of less installed on the remote host is prior to 653. It is, therefore, affected by a vulnerability as referenced in the SSA:2024-105-01 advisory.

 - less through 653 allows OS command execution via a newline character in the name of a file, because quoting is mishandled in filename.c. Exploitation typically requires use with attacker-controlled file names, such as the files extracted from an untrusted archive. Exploitation also requires the LESSOPEN environment variable, but this is set by default in many common cases. (CVE-2024-32487)

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 less package.
