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.
