Summary
Red Hat Security Advisory: less security update
Notes
Topic
An update for less is now available for Red Hat Enterprise Linux 9.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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.
