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.

Security readout for executives and security teams

This is an old Apple Mac OS X certificate-processing flaw. A malicious website or email could trigger unsafe handling of a crafted Certificate Revocation List and potentially crash an application or run arbitrary code. The source bundle identifies systems before Mac OS X 10.7.2 as affected. Exposure is most likely limited to legacy Apple Mac OS X systems older than 10.7.2 that process untrusted web or email content. Modern supported macOS versions are not identified as affected in the provided sources. Prioritize remediation where legacy Mac OS X systems still exist in business workflows. The issue is old, but the potential impact includes remote code execution through routine web or email activity. Mitigation focus: Upgrade affected Mac OS X systems to 10.7.2 or later per Apple guidance.; Retire or isolate unsupported legacy Mac OS X systems that cannot be updated.; Limit untrusted web and email handling on legacy systems until remediated..
