_______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2009:239 http://www.mandriva.com/security/ _______________________________________________________________________ Package : openssl Date : September 22, 2009 Affected: 2009.1 _______________________________________________________________________ Problem Description: Multiple vulnerabilities was discovered and corrected in openssl: Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote attackers to cause a denial of service (openssl s_client crash) and possibly have unspecified other impact via a DTLS packet, as demonstrated by a packet from a server that uses a crafted server certificate (CVE-2009-1379). The dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL before 1.0.0 Beta 2 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence DTLS handshake message, related to a fragment bug. (CVE-2009-1387) The NSS library library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spooof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large (CVE-2009-2409). This update provides a solution to these vulnerabilities. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1379 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1387 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-2409 _______________________________________________________________________ Updated Packages: Mandriva Linux 2009.1: 87fd48b517c4fe99dd2c9500c91b8324 2009.1/i586/libopenssl0.9.8-0.9.8k-1.2mdv2009.1.i586.rpm 1bd7bda2b2bdda4f214bde8844f7c783 2009.1/i586/libopenssl0.9.8-devel-0.9.8k-1.2mdv2009.1.i586.rpm cf880c3d0cc12b3330d378905e247398 2009.1/i586/libopenssl0.9.8-static-devel-0.9.8k-1.2mdv2009.1.i586.rpm e8661d33e2dc46c8fb558cc28bd9cec3 2009.1/i586/openssl-0.9.8k-1.2mdv2009.1.i586.rpm 4189b82f3522357d6e5df8b4958a4d6c 2009.1/SRPMS/openssl-0.9.8k-1.2mdv2009.1.src.rpm Mandriva Linux 2009.1/X86_64: 87c9306042676dbfc9d9d74164dc2bce 2009.1/x86_64/lib64openssl0.9.8-0.9.8k-1.2mdv2009.1.x86_64.rpm f0d77d0ee36f47dcd18bf872e236e2ac 2009.1/x86_64/lib64openssl0.9.8-devel-0.9.8k-1.2mdv2009.1.x86_64.rpm 950eac00b80ded525cb01f7f9e7ef707 2009.1/x86_64/lib64openssl0.9.8-static-devel-0.9.8k-1.2mdv2009.1.x86_64.rpm 17a67f2a09a0e79185187cb05e1f7f1f 2009.1/x86_64/openssl-0.9.8k-1.2mdv2009.1.x86_64.rpm 4189b82f3522357d6e5df8b4958a4d6c 2009.1/SRPMS/openssl-0.9.8k-1.2mdv2009.1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
