Name of the Vulnerable Software and Affected Versions dyld in Apple iOS versions 5.1.x through 6.1.3

Description A stack-based buffer overflow issue exists in the openSharedCacheFile function in dyld.cpp, which can be exploited by attackers using a long string in the DYLD SHARED CACHE DIR environment variable, making it easier to conduct untethering attacks.

Recommendations For dyld in Apple iOS versions 5.1.x through 6.1.3, consider restricting access to the DYLD SHARED CACHE DIR environment variable to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
