Ubuntu Security Notice USN-2883-1
January 28, 2016

openssl vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10


OpenSSL could be made to expose sensitive information over the network.

Software Description:
- openssl: Secure Socket Layer (SSL) cryptographic library and tools


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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.10:
  libssl1.0.0                     1.0.2d-0ubuntu1.3

After a standard system update you need to reboot your computer to make
all the necessary changes.
