-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3184-1 security@debian.org http://www.debian.org/security/ Alessandro Ghedini March 12, 2015 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : gnupg CVE ID : CVE-2014-3591 CVE-2015-0837 CVE-2015-1606 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 (crash) via crafted keyring files. For the stable distribution (wheezy), these problems have been fixed in version 1.4.12-7+deb7u7. For the upcoming stable distribution (jessie), these problems have been fixed in version 1.4.18-7. For the unstable distribution (sid), these problems have been fixed in version 1.4.18-7. We recommend that you upgrade your gnupg packages.
