CVSS: 5.0EPSS: 4%CPEs: 22EXPL: 0CVE-2014-4341 – krb5: denial of service flaws when handling padding length longer than the plaintext
https://notcve.org/view.php?id=CVE-2014-4341
MIT Kerberos 5 (aka krb5) before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read and application crash) by injecting invalid tokens into a GSSAPI application session. MIT Kerberos 5 (también conocido como krb5) anterior a 1.12.2 permite a atacantes remotos causar una denegación de servicio (sobrelectura de buffer y caída de aplicación) mediante la inyección de tokens inválido en una sesión de la aplicación GSSAPI. A buffer over-read flaw was found in the way MIT Kerberos handled certain requests. A remote, unauthenticated attacker who is able to inject packets into a client or server application's GSSAPI session could use this flaw to crash the application. • 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=7949 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://security.gentoo.org/glsa/glsa-201412-53.xml http://www.debian&# • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2013-6800
An unspecified third-party database module for the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.10.x allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request, a different vulnerability than CVE-2013-1418. Un módulo de base de datos de terceros sin especificar para Key Distribution Center (KDC) en MIT Kerberos 5 (también conocido como krb5) 1.10.x permite a usuarios remotos autenticados provocar una denegación de servicio (referencia a puntero NULL y cierre del demonio) a través de una petición manipulada, una vulnerabilidad diferente a CVE-2013-1418. It was found that if a KDC served multiple realms, certain requests could cause the setup_server_realm() function to dereference a NULL pointer. A remote, unauthenticated attacker could use this flaw to crash the KDC using a specially crafted request. • http://krbdev.mit.edu/rt/Ticket/Display.html?id=7757 http://www.securityfocus.com/bid/63770 https://github.com/krb5/krb5/commit/c2ccf4197f697c4ff143b8a786acdd875e70a89d https://access.redhat.com/security/cve/CVE-2013-6800 https://bugzilla.redhat.com/show_bug.cgi?id=1031499 • CWE-476: NULL Pointer Dereference •

The setup_server_realm function in main.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.7, when multiple realms are configured, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request. La función setup_server_realm en main.c en Key Distribution Center (KDC) de MIT Kerberos 5 (también conocido como krb5) anterior a la versión 1.10.7, cuando se configuran varios campos, permite a atacantes remotos provocar una denegación de servicio (referencia a un puntero NULL y cierre del demonio) a través de una petición manipulada. It was found that if a KDC served multiple realms, certain requests could cause the setup_server_realm() function to dereference a NULL pointer.
