CVE-2010-0433
Last modified
CVE-2010-0433 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 7.86% chance of exploitation in the next 30 days.
