As per Upstream advisory:
A double free bug was discovered when OpenSSL parses malformed DSA private keys and could lead to a DoS attack or memory corruption for applications that receive DSA private keys from untrusted sources. This scenario is considered rare.
This issue affects OpenSSL versions 1.0.2 and 1.0.1.
OpenSSL 1.0.2 users should upgrade to 1.0.2g OpenSSL 1.0.1 users should upgrade to 1.0.1s
This issue was reported to OpenSSL on 7th February 2016 by Adam Langley (Google/BoringSSL) using libFuzzer. The fix was developed by Dr Stephen Henson of OpenSSL.
A man-in-the-middle (MITM) attacker may be able to execute a padding oracle attack to decrypt traffic when a connection uses an AES-CBC cipher and the server runs on an Intel CPU supporting AES-NI. This is a common configuration for TLS servers.
The OpenSSL project has labelled this vulnerability high severity.
A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library.
An information disclosure vulnerability in Bouncy Castle could enable a local malicious application to gain access to user’s private information.

It was reported that possible use-after-free vulnerability in keyring facility, possibly leading to local privilege escalation, was found. Function joinsessionkeyring in security/keys/processkeys.c holds a reference to the requested keyring, but if that keyring is the same as the one being currently used by the process, the kernel wouldn't decrease keyring->usage before returning to userspace. The usage field can be possibly overflowed causing use-after-free on the keyring object.
