CVE-2010-1320: Double free vulnerability in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5)...

Double free vulnerability in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7.x and 1.8.x before 1.8.2 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a request associated with (1) renewal or (2) validation.

Security readout for executives and security teams

This flaw affects MIT Kerberos KDC servers, which issue authentication tickets. An authenticated remote user could send certain ticket renewal or validation requests that crash the KDC, potentially disrupting logins across dependent systems. The CVE also notes possible arbitrary code execution, but the provided sources do not confirm active exploitation. Exposure is mainly legacy MIT Kerberos KDC deployments or vendor packages that still run krb5 1.7.x or 1.8.x before 1.8.2. Modern supported distributions are unlikely to remain affected, but old appliances, embedded systems, or frozen server images should be checked. Treat this as urgent for any active legacy Kerberos KDC because a crash can block authentication-dependent business operations. If inventory confirms only modern patched Kerberos packages, residual priority is low and should be documented. Mitigation focus: Upgrade MIT Kerberos krb5 KDC to 1.8.2 or later.; Apply relevant OS vendor security updates from Ubuntu, Apple, Debian, or SUSE guidance.; Restrict KDC access to trusted networks where operationally possible..
