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)
