CVE-2014-4342: MIT Kerberos 5 (aka krb5) 1.7.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of s...

Security readout for executives and security teams

This flaw can let a remote attacker crash applications that use MIT Kerberos GSSAPI by sending invalid session tokens. The stated impact is denial of service, not data theft or system takeover. Business urgency depends on whether Kerberos-backed services are reachable by untrusted users or networks. Exposure is most likely on systems running vulnerable MIT krb5 libraries where GSSAPI-enabled applications accept sessions from remote or semi-trusted clients. The provided affected-product metadata is incomplete, so confirm through package and application inventory. Address during normal vulnerability remediation unless exposed Kerberos-backed services are business-critical or externally reachable. Escalate if crashes are observed or if vulnerable libraries support authentication for important production services. Mitigation focus: Upgrade MIT krb5 to 1.12.2 or later where applicable.; Apply vendor-fixed Kerberos packages from your operating system or platform advisory.; Prioritize internet-facing or partner-facing GSSAPI-enabled services..
