less-530-3.el8_10

The "less" utility is a text file browser that resembles "more", but allows users to move backwards in the file as well as forwards. Since "less" does not read the entire input file at startup, it also starts more quickly than ordinary text editors.

Security Fix(es):

* less: OS command injection (CVE-2024-32487)
* less: missing quoting of shell metacharacters in LESSCLOSE handling (CVE-2022-48624)

CVE-2022-48624
close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE.
CVE-2024-32487
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.
