CVE-2007-3749

Status: ModifiedHigh (7.8)—

The kernel in Apple Mac OS X 10.4 through 10.4.10 does not reset the current Mach Thread Port or Thread Exception Port when executing a setuid program, which allows local users to execute arbitrary code by creating the port before launching the setuid program, then writing to the address space of the setuid process.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
