openssl - security update

Multiple vulnerabilities have been discovered in OpenSSL, a Secure
Sockets Layer toolkit. The Common Vulnerabilities and Exposures project
identifies the following issues:

• CVE-2015-3194
  Loic Jonas Etienne of Qnective AG discovered that the signature
  verification routines will crash with a NULL pointer dereference if
  presented with an ASN.1 signature using the RSA PSS algorithm and
  absent mask generation function parameter. A remote attacker can
  exploit this flaw to crash any certificate verification operation
  and mount a denial of service attack.
• CVE-2015-3195
  Adam Langley of Google/BoringSSL discovered that OpenSSL will leak
  memory when presented with a malformed X509_ATTRIBUTE structure.
• CVE-2015-3196
  A race condition flaw in the handling of PSK identify hints was
  discovered, potentially leading to a double free of the identify
  hint data.

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.0.1e-2+deb7u18.

For the stable distribution (jessie), these problems have been fixed in
version 1.0.1k-3+deb8u2.

For the unstable distribution (sid), these problems have been fixed in
version 1.0.2e-1 or earlier.

We recommend that you upgrade your openssl packages.
