The (1) publickey_make_dss, (2) publickey_make_rsa, (3) signature_from_string, (4) ssh_do_sign, and (5) ssh_sign_session_id functions in keys.c in libssh before 0.5.3 free "an invalid pointer on an error path," which might allow remote attackers to cause a denial of service (crash) via unspecified vectors. Las funciones (1) publickey_make_dss, (2) publickey_make_rsa, (3) signature_from_string, (4) ssh_do_sign y (5) ssh_sign_session_id en keys.c en libssh en versiones anteriores a la 0.5.3 liberan "un puntero no válido en una ruta errónea", lo que podría permitir a atacantes remotos provocar una denegación de servicio (caída) a través de vectores no especificados. • http://lists.fedoraproject.org/pipermail/package-announce/2012-November/093313.html http://lists.fedoraproject.org/pipermail/package-announce/2012-November/093474.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00002.html http://lists.opensuse.org/opensuse-updates/2012-12/msg00016.html http://lists.opensuse.org/opensuse-updates/2013-01/msg00021.html http://www.debian.org/security/2012/dsa-2577 http://www.libssh.org/2012/11/20/libssh-0-5-3-security-release http://www. •

Multiple integer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (infinite loop or crash) and possibly execute arbitrary code via unspecified vectors, which triggers a buffer overflow, infinite loop, or possibly some other unspecified vulnerabilities. Múltiples desbordamientos de enteros en libssh antes de v0.5.3 permiten a atacantes remotos provocar una denegación de servicio (bucle infinito o caída) y posiblemente ejecutar código de su elección a través de vectores no especificados, lo que provoca un desbordamiento de búfer, bucle infinito, o posiblemente algunas vulnerabilidades no especificadas. • http://lists.fedoraproject.org/pipermail/package-announce/2012-November/093313.html http://lists.fedoraproject.org/pipermail/package-announce/2012-November/093474.html http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00002.html http://lists.opensuse.org/opensuse-updates/2012-12/msg00016.html http://lists.opensuse.org/opensuse-updates/2013-01/msg00021.html http://www.debian.org/security/2012/dsa-2577 http://www&# • CWE-189: Numeric Errors •
