Amazon Linux 2 : less (ALAS-2024-2547)

high Nessus Plugin ID 198271

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of less installed on the remote host is prior to 458-9. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2547 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update less' to update your system.
