Bypassing Same Origin Policy through Unsigned JavaScript Code in Mozilla Firefox and SeaMonkey

CVE-2011-2993 · HIGH Severity

AV:N/AC:M/AU:N/C:C/I:C/A:C

The implementation of digital signatures for JAR files in Mozilla Firefox 4.x through 5, SeaMonkey 2.x before 2.3, and possibly other products does not prevent calls from unsigned JavaScript code to signed code, which allows remote attackers to bypass the Same Origin Policy and gain privileges via a crafted web site, a different vulnerability than CVE-2008-2801.
