The kdb_ldap plugin in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 through 1.9.1, when the LDAP back end is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a kinit operation with incorrect string case for the realm, related to the is_principal_in_realm, krb5_set_error_message, krb5_ldap_get_principal, and process_as_req functions. El plug-in kdb_ldap en el centro de distribución de claves (KDC) en MIT Kerberos 5 (krb5) v1.9 a v1.9.1, cuando el back end LDAP es utilizado, permite a atacantes remotos provocar una denegación de servicio (puntero a NULL y caída del demonio) a través de una operación de kinit en la cadena incorrecta, en relación con la is_principal_in_realm, krb5_set_error_message, krb5_ldap_get_principal, y las funciones process_as_req. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=629558 http://web.mit.edu/kerberos/advisories/MITKRB5-SA-2011-006.txt http://www.kb.cert.org/vuls/id/659251 http://www.mandriva.com/security/advisories?name=MDVSA-2011:159 http://www.redhat.com/support/errata/RHSA-2011-1379.html https://access.redhat.com/security/cve/CVE-2011-1527 https://bugzilla.redhat.com/show_bug.cgi?id=737711 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2011-1526
ftpd.c in the GSS-API FTP daemon in MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.1 and earlier does not check the krb5_setegid return value, which allows remote authenticated users to bypass intended group access restrictions, and create, overwrite, delete, or read files, via standard FTP commands, related to missing autoconf tests in a configure script. ftpd.c en el demonio GSS-API FTP en MIT Kerberos Version 5 Applications (también conocido como krb5-appl) v1.0.1 y anteriores no comprueban el valor de retorno krb5_setegid, lo que permite que usuarios autenticados de forma remota evitar las restricciones de acceso de grupo, y crear, sobreescribir, borrar, o leer ficheros, a través de comandos FTP estándar, relacionado con test autoconfigurados olvidados en un script configurado. It was found that ftpd, a Kerberos-aware FTP server, did not properly drop privileges. On Red Hat Enterprise Linux 5, the ftpd daemon did not check for the potential failure of the krb5_setegid() function call. On systems where the set real, set effective, or set saved group ID system calls might fail, a remote FTP user could use this flaw to gain unauthorized read or write access to files that were owned by the root group. • http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062681.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062699.html http://lists.opensuse.org/opensuse-security-announce/2011-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00005.html http://lists.opensuse.org/opensuse-security-announce/201 • CWE-269: Improper Privilege Management •
