Multiple vulnerabilities were discovered in GnuPG, the GNU Privacy Guard: 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 via crafted keyring files.
