New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 3.6
SynopsisThe remote Debian host is missing a security-related update.
DescriptionKarthikeyan Bhargavan and Gaetan Leurent at INRIA discovered a flaw in the TLS 1.2 protocol which could allow the MD5 hash function to be used for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker could exploit this flaw to conduct collision attacks to impersonate a TLS server or an authenticated TLS client.
