CVE-2007-4268: Apple Mac OS X

High severity, CVSS 7.8. EPSS: 0.7% chance of exploitation in the next 30 days.

Integer signedness error in the Networking component in Apple Mac OS X 10.4 through 10.4.10 allows local users to execute arbitrary code via a crafted AppleTalk message with a negative value, which satisfies a signed comparison during mbuf allocation but is later interpreted as an unsigned value, which triggers a heap-based buffer overflow.

Affected products

• Apple Mac OS X: from 10.4.0, up to and including 10.4.10
