CVE-2010-0433  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Oracle:5 openssl to version 0:0.9.8e-12.el5_4.6 or higher.
This issue was patched in ELSA-2010-0162.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Oracle. See How to fix? for Oracle:5 relevant fixed versions and status.

The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but Kerberos configuration files cannot be opened, does not check a certain return value, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via SSL cipher negotiation, as demonstrated by a chroot installation of Dovecot or stunnel without Kerberos configuration files inside the chroot.
