Overview

CVE-2014-5352 is a high-severity vulnerability affecting mit kerberos_5. It was published on February 19, 2015 and has a CVSS 2.0 base score of 9.0 (HIGH).

This vulnerability has a CVSS 2.0 base score of 9.0, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical Description

The krb5_gss_process_context_token function in lib/gssapi/krb5/process_context_token.c in the libgssapi_krb5 library in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 does not properly maintain security-context handles, which allows remote authenticated users to cause a denial of service (use-after-free and double free, and daemon crash) or possibly execute arbitrary code via crafted GSSAPI traffic, as demonstrated by traffic to kadmind.

Remediation

Check the references section for vendor advisories and patches from mit. Update kerberos_5 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
