Ubuntu 12.04 LTS / 14.04 LTS / 16.04 LTS : libgcrypt11, libgcrypt20 vulnerability (USN-3065-1)
Medium Nessus Plugin ID 93046
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionFelix Dorre and Vladimir Klebanov discovered that Libgcrypt incorrectly handled mixing functions in the random number generator.
An attacker able to obtain 4640 bits from the RNG can trivially predict the next 160 bits of output.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected libgcrypt11 and / or libgcrypt20 packages.
