EulerOS 2.0 SP1 : krb5 (EulerOS-SA-2016-1076)

medium Nessus Plugin ID 99836

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the krb5 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- A NULL pointer dereference flaw was found in MIT Kerberos kadmind service. An authenticated attacker with permission to modify a principal entry could use this flaw to cause kadmind to dereference a NULL pointer and crash by supplying an empty DB argument to the modify_principal command, if kadmind was configured to use the LDAP KDB module. (CVE-2016-3119)

- A NULL pointer dereference flaw was found in MIT Kerberos krb5kdc service. An authenticated attacker could use this flaw to cause krb5kdc to dereference a NULL pointer and crash by making an S4U2Self request, if the restrict_anonymous_to_tgt option was set to true.(CVE-2016-3120)

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

Solution

Update the affected krb5 packages.
