Debian DSA-3884-1 : gnutls28 - security update

Medium Nessus Plugin ID 100852

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


The remote Debian host is missing a security-related update.


Hubert Kario discovered that GnuTLS, a library implementing the TLS and SSL protocols, does not properly decode a status response TLS extension, allowing a remote attacker to cause an application using the GnuTLS library to crash (denial of service).


Upgrade the gnutls28 packages.

For the stable distribution (jessie), this problem has been fixed in version 3.3.8-6+deb8u6.

For the upcoming stable distribution (stretch), this problem has been fixed in version 3.5.8-5+deb9u1.
