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

medium Nessus Plugin ID 14122
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


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.


Update the affected packages.
