| Description: | Summary:
The remote host is missing an update to openssl
announced via advisory MDVSA-2009:239.
Vulnerability Insight:
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.
Affected: 2009.1
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
