Slackware Security[slackware-security] less (SSA:2024-105-01)
New less packages are available for Slackware 15.0 and -current to
fix a security issue.
Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/less-653-i586-1_slack15.0.txz: Upgraded.
This update patches a security issue:
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.

(* Security fix *)
