This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

krb5 was updated to fix three security issues.

These security issues were fixed :

- CVE-2015-2695: Applications which call
gss_inquire_context() on a partially-established SPNEGO
context could have caused the GSS-API library to read
from a pointer using the wrong type, generally causing a
process crash. (bsc#952188).

- CVE-2015-2696: Applications which call
gss_inquire_context() on a partially-established IAKERB
context could have caused the GSS-API library to read
from a pointer using the wrong type, generally causing a
process crash. (bsc#952189).

- CVE-2015-2697: Incorrect string handling in
build_principal_va can lead to DOS (bsc#952190).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
