HP-UX Running OpenSSL Remote Unauthorized Information Disclosure Unauthorized Data Modification Denial of Service (DoS)

oval:org.mitre.oval:def:12260

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.
