USN-2883-1: OpenSSL vulnerability
Ubuntu Security Notice USN-2883-1
28th January, 2016
openssl vulnerability
A security issue affects these releases of Ubuntu and its
derivatives:
- Ubuntu 15.10
Summary
OpenSSL could be made to expose sensitive information over the network.
Software description
- openssl
– Secure Socket Layer (SSL) cryptographic library and tools
Details
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 version:
- Ubuntu 15.10:
-
libssl1.0.0
1.0.2d-0ubuntu1.3
To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make
all the necessary changes.

Red Hat Security Advisory 2016-0081-01
Red Hat Security Advisory 2016-0081-01 – KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM. An out-of-bounds read/write flaw was discovered in the way QEMU’s Firmware Configuration device emulation processed certain firmware configurations. A privileged guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
