8 January 2016
GnuTLS could be made to expose sensitive information over the network.
Releases
Packages
Details
Karthikeyan Bhargavan and Gaetan Leurent discovered that GnuTLS incorrectly
allowed MD5 to be used for TLS 1.2 connections. If a remote attacker were
able to perform a machine-in-the-middle attack, this flaw could be exploited to
view sensitive information.
