Mandriva Linux Security Advisory : openssl (MDVSA-2009:310)

Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

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 provided for Corporate Desktop 2008.0
customers

The updated packages have been patched to prevent this.
