Hi,

The following vulnerability was published for less.

CVE-2024-32487[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
