CVE-2007-4268 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.67% chance of exploitation in the next 30 days.
