CVE-2008-1440

Status: ModifiedHigh (7.1)—

Microsoft Windows XP SP2 and SP3, and Server 2003 SP1 and SP2, does not properly validate the option length field in Pragmatic General Multicast (PGM) packets, which allows remote attackers to cause a denial of service (infinite loop and system hang) via a crafted PGM packet, aka the "PGM Invalid Length Vulnerability."

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).
