Debian dsa-5679 : less - security update

high Nessus Plugin ID 194970

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 / 12 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5679 advisory.

- close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)

- 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 these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the less packages.
