CVE-2007-3726 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.13% chance of exploitation in the next 30 days.
