SUSE SLED12 / SLES12 Security Update : krb5 (SUSE-SU-2015:1897-1)

high Nessus Plugin ID 86754
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
