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.
