MIT Kerberos 5 (aka krb5) through 1.13.1 incorrectly expects that a krb5_read_message data field is represented as a string ending with a '\0' character, which allows remote attackers to (1) cause a denial of service (NULL pointer dereference) via a zero-byte version string or (2) cause a denial of service (out-of-bounds read) by omitting the '\0' character, related to appl/user_user/server.c and lib/krb5/krb/recvauth.c.

Security readout for executives and security teams

CVE-2014-5355 is a denial-of-service flaw in MIT Kerberos 5 through 1.13.1. A remote attacker could send malformed Kerberos message data that crashes affected Kerberos-related code. The reported impact is service disruption, not data theft or code execution, based on the provided sources. Exposure is most likely on legacy systems running MIT krb5 through 1.13.1 or vendor packages covered by the Red Hat, Debian, SUSE, Ubuntu, Oracle, or Mandriva advisories. Internet or partner-reachable Kerberos-enabled services increase operational risk. Treat this as a moderate operational resilience issue. Patch legacy Kerberos infrastructure during normal security maintenance, escalating priority where authentication services are externally reachable or business-critical. Mitigation focus: Apply vendor krb5 security updates referenced by the relevant Linux or Unix distribution.; For source builds, incorporate the referenced MIT krb5 fix or vendor-advised patched release.; Prioritize Kerberos services reachable by untrusted networks or external users..
