Mandrake Linux Security Advisory : openssl (MDKSA-2004:023)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

A vulnerability was discovered by the OpenSSL group using the
Codenomicon TLS Test Tool. The test uncovered a NULL pointer
assignment in the do_change_cipher_spec() function whih could be
abused by a remote attacker crafting a special SSL/TLS handshake
against a server that used the OpenSSL library in such a way as to
cause OpenSSL to crash. Depending on the application in question, this
could lead to a Denial of Service (DoS). This vulnerability affects
both OpenSSL 0.9.6 (0.9.6c-0.9.6k) and 0.9.7 (0.9.7a-0.9.7c). CVE has
assigned CVE-2004-0079 to this issue.

Another vulnerability was discovered by Stephen Henson in OpenSSL
versions 0.9.7a-0.9.7c; there is a flaw in the SSL/TLS handshaking
code when using Kerberos ciphersuites. A remote attacker could perform
a carefully crafted SSL/TLS handshake against a server configured to
use Kerberos ciphersuites in such a way as to cause OpenSSL to crash.
CVE has assigned CVE-2004-0112 to this issue.

Mandrakesoft urges users to upgrade to the packages provided that have
been patched to protect against these problems. We would also like to
thank NISCC for their assistance in coordinating the disclosure of
these problems.

Please note that you will need to restart any SSL-enabled services for
the patch to be effective, including (but not limited to) Apache,
OpenLDAP, etc.

Solution :

Update the affected packages.
