TITLE

Apple Mac OS X of libsecurity Vulnerable to arbitrary code execution

DESCRIPTION

libsecurity in Apple Mac OS X before 10.7.2 does not properly handle errors during processing of a nonstandard extension in a Certificate Revocation list (CRL), which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) a crafted (1) web site or (2) e-mail message. The update addresses new vulnerabilities that affect Application Firewall, ATS, CFNetwork, CoreMedia, CoreProcesses, CoreStorage, File Systems, IOGraphics, Kernel, MediaKit, Open Directory, QuickTime, SMB File Server, User Documentation, and libsecurity. Apple Mac OS X is prone to a remote code-execution vulnerability that has been addressed in Security Update 2011-006. Successful exploitation may allow an attacker to execute arbitrary code in the context of the application that uses the affected library. Failed exploit attempts may result in a denial-of-service condition. The following versions are affected: OS X 10.7 and 10.7.1 OS X Server 10.7 and 10.7.1 NOTE: This issue was previously discussed in BID 50085 (Apple Mac OS X Prior to 10.7.2 Multiple Security Vulnerabilities) but has been given its own record to better document it.
