The Debian security team deemed this advisory irrelevant for Debian:12.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rar package and not the rar package as distributed by Debian.
RARLAB WinRAR before 6.23 allows attackers to execute arbitrary code when a user attempts to view a benign file within a ZIP archive. The issue occurs because a ZIP archive may include a benign file (such as an ordinary .JPG file) and also a folder that has the same name as the benign file, and the contents of the folder (which may include executable content) are processed during an attempt to access only the benign file. This was exploited in the wild in April through October 2023.
