CVE-2008-1030: Apple Mac OS X

High severity, CVSS 10.0. EPSS: 4.7% chance of exploitation in the next 30 days.

Integer overflow in the CFDataReplaceBytes function in the CFData API in CoreFoundation in Apple Mac OS X before 10.5.3 allows context-dependent attackers to execute arbitrary code or cause a denial of service (crash) via an invalid length argument, which triggers a heap-based buffer overflow.

• Apple Mac OS X Server: version 10.4.11 only; version 10.5 only; version 10.5.1 only; version 10.5.2 only
