Ubuntu 15.10 : openssl vulnerability (USN-2883-1)

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


Synopsis :

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

Description :

Antonio Sanso discovered that OpenSSL reused the same private DH
exponent for the life of a server process when configured with a X9.42
style parameter file. This could allow a remote attacker to possibly
discover the server's private DH exponent when being used with
non-safe primes.

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 libssl1.0.0 package.

Risk factor :

Low / CVSS Base Score : 2.6
(CVSS2#AV:N/AC:H/Au:N/C:P/I:N/A:N)
CVSS Temporal Score : 1.9
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
