CVE-2005-3668

Status: ModifiedMedium (5)—

Multiple buffer overflows in multiple unspecified implementations of Internet Key Exchange version 1 (IKEv1) have multiple unspecified attack vectors and impacts related to denial of service, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of information in the original sources, it is likely that this candidate will be REJECTed once it is known which implementations are actually vulnerable.

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).
