https://notcve.org/view.php?id=CVE-2014-4343
Double free vulnerability in the init_ctx_reselect function in the SPNEGO initiator in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.10.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via network traffic that appears to come from an intended acceptor, but specifies a security mechanism different from the one proposed by the initiator. Vulnerabilidad de doble liberación en la función init_ctx_reselect en el iniciador SPNEGO en lib/gssapi/spnego/spnego_mech.c en MIT Kerberos 5 (también conocido como krb5) 1.10.x hasta 1.12.x anterior a 1.12.2 permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) o posiblemente ejecutar código arbitrario a través de trafico de la red que parece venir de un aceptador intencionado, pero especifica un mecanismo de seguridad diferente al propuesto por el iniciador. A double-free flaw was found in the MIT Kerberos SPNEGO initiators. An attacker able to spoof packets to appear as though they are from an GSSAPI acceptor could use this flaw to crash a client application that uses MIT Kerberos. • http://advisories.mageia.org/MGASA-2014-0345.html http://aix.software.ibm.com/aix/efixes/security/nas_advisory1.asc http://krbdev.mit.edu/rt/Ticket/Display.html?id=7969 http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136360.html http://rhn.redhat.com/errata/RHSA-2015-0439.html http://secunia.com/advisories/59102 http://secunia.com/advisories/60082 http://secunia.com/advisories/60448 http://secunia.com/advisories/61052 http://security.gentoo.org/glsa/glsa • CWE-415: Double Free CWE-416: Use After Free •
