This is related to vulnerability #4 in: SA46377 2) Multiple errors within the CoreGraphics component when handling FreeType fonts can be exploited to corrupt memory. 3) A logic error within the mmap system call when checking valid flag combinations can be exploited to bypass codesigning checks and execute unsigned code. Successful exploitation of this vulnerability requires that the user is tricked into installing a malicious App. 4) An error within libinfo when handling DNS name lookups can be exploited to spoof lookups. Successful exploitation of vulnerabilities #2 and #3 may allow execution of arbitrary code. SOLUTION: Apply iOS 5.0.1 Software Update (downloadable and installable via iTunes).
