GLSA-200701-14 : Mod_auth_kerb: Denial of Service

medium Nessus Plugin ID 24250

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200701-14 (Mod_auth_kerb: Denial of Service)

 Mod_auth_kerb improperly handles component byte encoding in the der_get_oid() function, allowing for a buffer overflow to occur if there are no components which require more than one byte for encoding.
 Impact :

 An attacker could try to access a Kerberos protected resource on an Apache server with an incorrectly configured service principal and crash the server process. It is important to note that this buffer overflow is not known to allow for the execution of code.
 Workaround :

 There is no known workaround at this time.

Solution

All mod_auth_kerb users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=www-apache/mod_auth_kerb-5.0_rc7-r1'
