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

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


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.

Risk factor :

Low / CVSS Base Score : 1.9
(CVSS2#AV:L/AC:M/Au:N/C:P/I:N/A:N)
CVSS Temporal Score : 1.7
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
