-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2009:310 http://www.mandriva.com/security/ _______________________________________________________________________ Package : openssl Date : December 3, 2009 Affected: 2008.0 _______________________________________________________________________ Problem Description: Multiple security vulnerabilities has been identified and fixed in OpenSSL: The dtls1_buffer_record function in ssl/d1_pkt.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote attackers to cause a denial of service (memory consumption) via a large series of future epoch DTLS records that are buffered in a queue, aka DTLS record buffer limitation bug. (CVE-2009-1377) Multiple memory leaks in the dtls1_process_out_of_seq_message function in ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote attackers to cause a denial of service (memory consumption) via DTLS records that (1) are duplicates or (2) have sequence numbers much greater than current sequence numbers, aka DTLS fragment handling memory leak. (CVE-2009-1378) 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). ssl/s3_pkt.c in OpenSSL before 0.9.8i allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a DTLS ChangeCipherSpec packet that occurs before ClientHello (CVE-2009-1386). 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). A regression was found with the self signed certificate signatures checking after applying the fix for CVE-2009-2409. An upstream patch has been applied to address this issue. Packages for 2008.0 are being provided due to extended support for Corporate products. The updated packages have been patched to prevent this. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1377 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1378 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1379 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1386 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1387 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-2409 http://marc.info/?l=openssl-cvs&m=124508133203041&w=2 https://qa.mandriva.com/54349 _______________________________________________________________________ Updated Packages: Mandriva Linux 2008.0: 5e5cebd5417fa8da31e5fb439832f4a9 2008.0/i586/libopenssl0.9.8-0.9.8e-8.4mdv2008.0.i586.rpm 56b10d47a9c0522a1d685851301ec3ed 2008.0/i586/libopenssl0.9.8-devel-0.9.8e-8.4mdv2008.0.i586.rpm c5689cbe8983c60b21f885bb417fa93d 2008.0/i586/libopenssl0.9.8-static-devel-0.9.8e-8.4mdv2008.0.i586.rpm f6998620b5cf142898da1b029e055756 2008.0/i586/openssl-0.9.8e-8.4mdv2008.0.i586.rpm 81ed32097a16b03713c16e46e8fae15a 2008.0/SRPMS/openssl-0.9.8e-8.4mdv2008.0.src.rpm Mandriva Linux 2008.0/X86_64: 4a8bfb0af6be2dc3b998b34692df9c03 2008.0/x86_64/lib64openssl0.9.8-0.9.8e-8.4mdv2008.0.x86_64.rpm a38da1e95cd3883a486cf67312031591 2008.0/x86_64/lib64openssl0.9.8-devel-0.9.8e-8.4mdv2008.0.x86_64.rpm 82fd48fc11975ae589b7818dce0a9973 2008.0/x86_64/lib64openssl0.9.8-static-devel-0.9.8e-8.4mdv2008.0.x86_64.rpm a567f0cc7825b1f73e749d96f50a2f2e 2008.0/x86_64/openssl-0.9.8e-8.4mdv2008.0.x86_64.rpm 81ed32097a16b03713c16e46e8fae15a 2008.0/SRPMS/openssl-0.9.8e-8.4mdv2008.0.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
