The hash_buffer function in schnorr.c in OpenSSH through 6.4, when Makefile.inc is modified to enable the J-PAKE protocol, does not initialize certain data structures, which might allow remote attackers to cause a denial of service (memory corruption) or have unspecified other impact via vectors that trigger an error condition. La función hash_buffer en schnorr.c en OpenSSH hasta 6.4 cuando Makefile.inc se modifica para habilitar el protocolo J-PAKE, no inicializa ciertas estructuras de datos, lo que podría permitir a atacantes remotos provocar una denegación de servicio (corrupción de memoria) o tienen impacto no especificado a través de vectores que provocan una condición de error. • http://marc.info/?l=bugtraq&m=141576985122836&w=2 http://marc.info/?l=bugtraq&m=144050155601375&w=2 http://openwall.com/lists/oss-security/2014/01/29/10 http://openwall.com/lists/oss-security/2014/01/29/2 http://osvdb.org/102611 http://secunia.com/advisories/60184 http://www-01.ibm.com/support/docview.wss?uid=isg3T1020637 http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/Attic/schnorr.c.diff?r1=1.9%3Br2=1.10%3Bf=h http://www.openbsd.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The mm_newkeys_from_blob function in monitor_wrap.c in sshd in OpenSSH 6.2 and 6.3, when an AES-GCM cipher is used, does not properly initialize memory for a MAC context data structure, which allows remote authenticated users to bypass intended ForceCommand and login-shell restrictions via packet data that provides a crafted callback address. La función mm_newkeys_from_blob en monitor_wrap.c de sshd en OpenSSH 6.2 y 6.3, cuando se utiliza el cifrado AES-GCM, no inicia correctamente la memoria para una estructura de datos de contexto MAC, lo que permite a usuarios remotos autenticados evadir intencionadamente ForceCommand y restricciones login-shell a través de un paquete de datos que proporciona una dirección de rellamada manipulada. • http://lists.opensuse.org/opensuse-security-announce/2013-11/msg00017.html http://marc.info/?l=bugtraq&m=141576985122836&w=2 http://openwall.com/lists/oss-security/2013/11/08/3 http://www.openssh.com/txt/gcmrekey.adv http://www.ubuntu.com/usn/USN-2014-1 • CWE-264: Permissions, Privileges, and Access Controls •
