NVD Description

Note: Versions mentioned in the description apply only to the upstream unrar-nonfree package and not the unrar-nonfree package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Integer signedness error in the SET_VALUE function in rarvm.cpp in unrar 3.70 beta 3, as used in products including WinRAR and RAR for OS X, allows user-assisted remote attackers to cause a denial of service (crash) via a crafted RAR archive that causes a negative signed number to be cast to a large unsigned number.
