CVE-2008-3637

Status: ModifiedHigh (8.8)—

The Hash-based Message Authentication Code (HMAC) provider in Java on Apple Mac OS X 10.4.11, 10.5.4, and 10.5.5 uses an uninitialized variable, which allows remote attackers to execute arbitrary code via a crafted applet, related to an "error checking issue."

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).
