CVE-2008-0948 – krb5: incorrect handling of high-numbered file descriptors in RPC library
https://notcve.org/view.php?id=CVE-2008-0948
Buffer overflow in the RPC library (lib/rpc/rpc_dtablesize.c) used by libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.2.2, and probably other versions before 1.3, when running on systems whose unistd.h does not define the FD_SETSIZE macro, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by triggering a large number of open file descriptors. Un desbordamiento de búfer en la biblioteca RPC (lib/rpc/rpc_dtablesize.c) utilizada por libgssrpc y kadmind en MIT Kerberos 5 (krb5) versión 1.2.2, y probablemente otras versiones anteriores a 1.3, cuando se ejecuta en sistemas cuyo unistd.h no define la macro FD_SETSIZE, lo que permite a los atacantes remotos causar una denegación de servicio (bloqueo) y posiblemente ejecutar código arbitrario mediante la activación de un gran número de descriptores de archivos abiertos. • http://lists.opensuse.org/opensuse-security-announce/2008-03/msg00006.html http://marc.info/?l=bugtraq&m=130497213107107&w=2 http://secunia.com/advisories/29423 http://secunia.com/advisories/29424 http://secunia.com/advisories/29428 http://secunia.com/advisories/29663 http://secunia.com/advisories/30535 http://securityreason.com/securityalert/3752 http://support.novell.com/docs/Readmes/InfoDocument/patchbuilder/readme_5022520.html http://support.novell.com/docs/Readmes/InfoDocument/patchbuilder • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVE-2007-5894
https://notcve.org/view.php?id=CVE-2007-5894
The reply function in ftpd.c in the gssftp ftpd in MIT Kerberos 5 (krb5) does not initialize the length variable when auth_type has a certain value, which has unknown impact and remote authenticated attack vectors. NOTE: the original disclosure misidentifies the conditions under which the uninitialized variable is used. NOTE: the vendor disputes this issue, stating " The 'length' variable is only uninitialized if 'auth_type' is neither the 'KERBEROS_V4' nor 'GSSAPI'; this condition cannot occur in the unmodified source code. ** EN DISPUTA ** La función de respuesta en ftpd.c en gssftp ftpd en MIT Kerberos 5 (krb5) no inicializa la variable de longitud cuando auth_type tiene un cierto valor, que tiene un impacto desconocido y vectores de ataque autenticados remotos. NOTA: la divulgación original identifica erróneamente las condiciones bajo las cuales se utiliza la variable no inicializada. NOTA: el proveedor discute este problema, indicando que "la variable 'longitud' solo no se inicializa si 'auth_type' no es ni 'KERBEROS_V4' ni 'GSSAPI'; esta condición no puede ocurrir en el código fuente no modificado". • http://bugs.gentoo.org/show_bug.cgi?id=199205 http://osvdb.org/44333 http://seclists.org/fulldisclosure/2007/Dec/0176.html http://seclists.org/fulldisclosure/2007/Dec/0321.html http://secunia.com/advisories/28636 http://secunia.com/advisories/29457 http://wiki.rpath.com/Advisories:rPSA-2008-0112 http://wiki.rpath.com/wiki/Advisories:rPSA-2008-0112 http://www.novell.com/linux/security/advisories/suse_security_summary_report.html http://www.securityfocus.com/archive/1/489883 •
