[DLA 176-1] mono security update

Package : mono
Version : 2.6.7-5.1+deb6u1
CVE ID : CVE-2015-2318 CVE-2015-2319 CVE-2015-2320
Debian Bug : 780751

Three issues with Mono's TLS stack are addressed.

CVE-2015-2318

Mono's implementation of the SSL/TLS stack failed to check
the order of the handshake messages. Which would allow
various attacks on the protocol to succeed. ("SKIP-TLS")

CVE-2015-2319

Mono's implementation of SSL/TLS also contained support for
the weak EXPORT cyphers and was susceptible to the FREAK attack.

CVE-2015-2320

Mono contained SSLv2 fallback code, which is no longer needed
and can be considered insecure.

Package : openssl
CVE ID : CVE-2015-0209 CVE-2015-0286 CVE-2015-0287 CVE-2015-0288
CVE-2015-0289 CVE-2015-0292

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

CVE-2015-0286

Stephen Henson discovered that the ASN1_TYPE_cmp() function
can be crashed, resulting in denial of service.

CVE-2015-0287

Emilia Kaesper discovered a memory corruption in ASN.1 parsing.

CVE-2015-0289

Michal Zalewski discovered a NULL pointer dereference in the
PKCS#7 parsing code, resulting in denial of service.

CVE-2015-0292

It was discovered that missing input sanitising in base64 decoding
might result in memory corruption.

CVE-2015-0209

It was discovered that a malformed EC private key might result in
memory corruption.

CVE-2015-0288

It was discovered that missing input sanitising in the
X509_to_X509_REQ() function might result in denial of service.

For the stable distribution (wheezy), these problems have been fixed in
version 1.0.1e-2+deb7u15. In this update the export ciphers are removed
from the default cipher list.

We recommend that you upgrade your openssl packages.
