 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.
