Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-175-1)
Summary:	The remote host is missing an update for the Debian 'gnupg' package(s) announced via the DLA-175-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'gnupg' package(s) announced via the DLA-175-1 advisory. Vulnerability Insight: 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 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. Affected Software/OS: 'gnupg' package(s) on Debian 6. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
