Name of the Vulnerable Software and Affected Versions libarchive versions prior to 3.2.0

Description The issue allows remote attackers to cause a denial of service, resulting in a crash, by providing a crafted 7z file. This is related to the 7z folder struct in the archive read support format 7zip.c file, specifically affecting the read CodersInfo function.

Recommendations For versions prior to 3.2.0, update to version 3.2.0 or later to resolve the issue. As a temporary workaround, consider avoiding the use of crafted 7z files that could trigger the denial of service.
