CVE-2014-3591
The Elgamal decryption routine was susceptible to a side-channel attack discovered by researchers of Tel Aviv University. Ciphertext blinding was enabled to counteract it. Note that this may have a quite noticeable impact on Elgamal decryption performance.
CVE-2015-0837
The modular exponentiation routine mpi_powm() was susceptible to a side-channel attack caused by data-dependent timing variations when accessing its internal pre-computed table.
CVE-2015-1606
The keyring parsing code did not properly reject certain packet types not belonging in a keyring, which caused an access to memory already freed. This could allow remote attackers to cause a denial of service (crash) via crafted keyring files.
For the oldstable distribution (squeeze), those problems have been fixed in version 1.4.10-4+squeeze7.
For the stable distribution (wheezy), these problems have been fixed in version 1.4.12-7+deb7u7.
We recommend that you upgrade your gnupg packages.");
