Launch Services in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 allows remote attackers to cause a denial of service (persistent Finder crash) via a crafted Mach-O executable that triggers an out-of-bounds memory read.

Security readout for executives and security teams

This is a legacy Apple Mac OS X denial-of-service issue. An attacker could provide a specially crafted Mach-O executable that makes Finder crash persistently. The sources describe disruption, not data theft or code execution. Exposure is mainly legacy Macs still running Mac OS X 10.4.11 or 10.5 before 10.5.7, especially systems that process untrusted downloaded, emailed, or shared executable files. Treat this as a legacy availability risk. It is unlikely to affect modern fleets, but any remaining affected Macs should be patched, isolated, or retired because user disruption can be persistent. Mitigation focus: Apply Apple’s vendor-advised fixed release or security update for affected Mac OS X versions.; Retire or isolate Mac OS X 10.4.11 and pre-10.5.7 systems where possible.; Restrict receipt and execution of untrusted Mach-O files on legacy Macs..
