_______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:166 http://www.mandriva.com/security/ _______________________________________________________________________ Package : gnutls Date : September 19, 2006 Affected: 2006.0, Corporate 4.0 _______________________________________________________________________ Problem Description: verify.c in GnuTLS before 1.4.4, when using an RSA key with exponent 3, does not properly handle excess data in the digestAlgorithm.parameters field when generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents GnuTLS from correctly verifying X.509 and other certificates that use PKCS, a variant of CVE-2006-4339. The provided packages have been patched to correct this issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4790 _______________________________________________________________________ Updated Packages: Mandriva Linux 2006.0: 7cb7aa3309af51dc44ca8bc9f855bb9b 2006.0/i586/gnutls-1.0.25-2.2.20060mdk.i586.rpm e30b5de1b0500830cfbcfbb7a845967d 2006.0/i586/libgnutls11-1.0.25-2.2.20060mdk.i586.rpm ddbe8a9d665b50a4614fee5251a8dc39 2006.0/i586/libgnutls11-devel-1.0.25-2.2.20060mdk.i586.rpm aea1556e219f37a6f4be8dadce721830 2006.0/SRPMS/gnutls-1.0.25-2.2.20060mdk.src.rpm Mandriva Linux 2006.0/X86_64: bd9f806eb2319b5d258d142154011650 2006.0/x86_64/gnutls-1.0.25-2.2.20060mdk.x86_64.rpm b8046dacc5e4fd5cd11acd7139fba8d9 2006.0/x86_64/lib64gnutls11-1.0.25-2.2.20060mdk.x86_64.rpm f26c571f9379dcae4efe5ccb5ddd1bce 2006.0/x86_64/lib64gnutls11-devel-1.0.25-2.2.20060mdk.x86_64.rpm e30b5de1b0500830cfbcfbb7a845967d 2006.0/x86_64/libgnutls11-1.0.25-2.2.20060mdk.i586.rpm ddbe8a9d665b50a4614fee5251a8dc39 2006.0/x86_64/libgnutls11-devel-1.0.25-2.2.20060mdk.i586.rpm aea1556e219f37a6f4be8dadce721830 2006.0/SRPMS/gnutls-1.0.25-2.2.20060mdk.src.rpm Corporate 4.0: a2254e8a31891b8bcc609f3cf13c62bb corporate/4.0/i586/gnutls-1.0.25-2.2.20060mlcs4.i586.rpm 41b00f4035f895b1e7b51522d1b31342 corporate/4.0/i586/libgnutls11-1.0.25-2.2.20060mlcs4.i586.rpm 2e74d9730bb73ec4cd4ccd584bd184b9 corporate/4.0/i586/libgnutls11-devel-1.0.25-2.2.20060mlcs4.i586.rpm 1e1ff2a8e7eabe7d152c98076f564476 corporate/4.0/SRPMS/gnutls-1.0.25-2.2.20060mlcs4.src.rpm Corporate 4.0/X86_64: 05843e5fd72d31c80c5d8218cf18d812 corporate/4.0/x86_64/gnutls-1.0.25-2.2.20060mlcs4.x86_64.rpm 112708823292a1f1ca17fa68daac8373 corporate/4.0/x86_64/lib64gnutls11-1.0.25-2.2.20060mlcs4.x86_64.rpm a0eaae0c87a0a56ef69a11c8db598fb8 corporate/4.0/x86_64/lib64gnutls11-devel-1.0.25-2.2.20060mlcs4.x86_64.rpm 41b00f4035f895b1e7b51522d1b31342 corporate/4.0/x86_64/libgnutls11-1.0.25-2.2.20060mlcs4.i586.rpm 2e74d9730bb73ec4cd4ccd584bd184b9 corporate/4.0/x86_64/libgnutls11-devel-1.0.25-2.2.20060mlcs4.i586.rpm 1e1ff2a8e7eabe7d152c98076f564476 corporate/4.0/SRPMS/gnutls-1.0.25-2.2.20060mlcs4.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
