CVE-2012-0884

Ivan Nestlerode discovered a weakness in the CMS and PKCS #7 implementations that could allow an attacker to decrypt data via a Million Message Attack (MMA).

CVE-2012-1165

It was discovered that a NULL pointer could be dereferenced when parsing certain S/MIME messages, leading to denial of service.

CVE-2012-2110

Tavis Ormandy, Google Security Team, discovered a vulnerability in the way DER-encoded ASN.1 data is parsed that can result in a heap overflow.

Additionally, the fix for CVE-2011-4619 has been updated to address an issue with SGC handshakes.

Tomas Hoger, Red Hat, discovered that the fix for CVE-2012-2110 for the 0.9.8 series of OpenSSL was incomplete. It has been assigned the CVE-2012-2131 identifier.

For the stable distribution (squeeze), these problems have been fixed in version 0.9.8o-4squeeze12.

For the testing distribution (wheezy), these problems will be fixed soon.

For the unstable distribution (sid), these problems have been fixed in version 1.0.1a-1.

We recommend that you upgrade your openssl packages.");
