CVSS 7.5
CVE-2022-48624 WRITEUP HIGH WRITEUP
less < 606 - OS Command Injection via LESSCLOSE
close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE.
CVSS 7.8
CVE-2024-32487 WRITEUP HIGH WRITEUP
less < 653 - OS Command Execution via Newline in Filename
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.
CVSS 8.6
