1. Summary:
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.
2. Relevant releases/architectures:

3. Description:
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)
