Summary

Moderate: less security update

Details

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: crafted data can result in "less -R" not filtering ANSI escape sequences sent to the terminal (CVE-2022-46663)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
