Ubuntu 12.04 LTS / 12.10 / 13.10 : libssh vulnerability (USN-2145-1)

low Nessus Plugin ID 72980

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Aris Adamantiadis discovered that libssh allowed the OpenSSL PRNG state to be reused when implementing forking servers. This could allow an attacker to possibly obtain information about the state of the PRNG and perform cryptographic attacks.

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.

Solution

Update the affected libssh-4 package.
