The SSL implementation in Apple Safari before 5.1.1 on Mac OS X before 10.7 accesses uninitialized memory during the processing of X.509 certificates, which allows remote web servers to execute arbitrary code via a crafted certificate.

Security readout for executives and security teams

A malicious web server could potentially compromise a vulnerable legacy Safari browser by presenting a crafted X.509 certificate. The issue is tied to uninitialized memory handling in Safari's SSL implementation before version 5.1.1 on Mac OS X before 10.7. Exposure appears limited to legacy Apple Safari versions before 5.1.1 on Mac OS X before 10.7. Modern environments are mainly at risk if old Macs or frozen browser images remain in use. Treat this as high priority only where legacy Safari or pre-10.7 Mac OS X remains operational. For current managed fleets, priority is inventory confirmation and legacy asset retirement rather than emergency response. Mitigation focus: Upgrade affected Safari installations to version 5.1.1 or later where supported.; Review Apple advisory HT5000 and APPLE-SA-2011-10-12-4 for vendor guidance.; Retire or isolate unsupported Mac OS X before 10.7 systems..
