-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:154 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : gnupg Date : March 29, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Updated gnupg, gnupg2 and libgcrypt packages fix security vulnerabilities: GnuPG versions before 1.4.17 and 2.0.24 are vulnerable to a denial of service which can be caused by garbled compressed data packets which may put gpg into an infinite loop (CVE-2014-4617). The libgcrypt library before version 1.5.4 is vulnerable to an ELGAMAL side-channel attack (CVE-2014-5270). GnuPG before 1.4.19 is vulnerable to a side-channel attack which can potentially lead to an information leak (CVE-2014-3591). GnuPG before 1.4.19 is vulnerable to a side-channel attack on data-dependent timing variations in modular exponentiation, which can potentially lead to an information leak (CVE-2015-0837). The gnupg and gnupg2 package has been patched to correct these issues. GnuPG2 is vulnerable to these issues through the libgcrypt library. The issues were fixed in libgcrypt 1.6.3. The libgcrypt package in Mandriva, at version 1.5.4, was only vulnerable to the CVE-2014-3591 issue. It has also been patched to correct this issue. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3591 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-4617 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-5270 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0837 http://advisories.mageia.org/MGASA-2014-0365.html http://advisories.mageia.org/MGASA-2015-0104.html http://advisories.mageia.org/MGASA-2014-0276.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: a1f0d486301a8da6084b6986b069a60a mbs2/x86_64/gnupg-1.4.16-2.1.mbs2.x86_64.rpm b902c66b91d7a5ecc1c93d580a2028a3 mbs2/x86_64/gnupg2-2.0.22-4.1.mbs2.x86_64.rpm 0d393d04f70b58c5692b2c28e5c62cc3 mbs2/x86_64/lib64gcrypt11-1.5.4-1.mbs2.x86_64.rpm 8ed5b1f7f83c843fbe0d3aa439417b06 mbs2/x86_64/lib64gcrypt-devel-1.5.4-1.mbs2.x86_64.rpm 6fc7d8af6e5cee8e6079b58de0508bf5 mbs2/SRPMS/gnupg-1.4.16-2.1.mbs2.src.rpm 932cd673c4fa7ab22f6e02b6d47f9ed3 mbs2/SRPMS/gnupg2-2.0.22-4.1.mbs2.src.rpm ff815ad77f30a8c5acedc7915e752b75 mbs2/SRPMS/libgcrypt-1.5.4-1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
