The (1) remote_glob function in sftp-glob.c and the (2) process_put function in sftp.c in OpenSSH 5.8 and earlier, as used in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, OpenBSD 4.7, and other products, allow remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in SSH_FXP_STAT requests to an sftp daemon, a different vulnerability than CVE-2010-2632. La (1) función remote_glob en sftp-glob.c y (2) la función process_put en sftp.c en OpenSSH v5.8 y versiones anteriores, como se usa en FreeBSD v7.3 y v8.1, NetBSD v5.0.2, OpenBSD v4.7 y otros productos, permiten a usuarios remotos autenticados causar una denegación de servicio (por excesivo uso de CPU y consumo de memoria) a través de expresiones glob debidamente modificadas que no coinciden con ningún nombre de ruta, como lo demuestran las expresiones glob en las solicitudes SSH_FXP_STAT a un demonio de sftp. Se trata de una vulnerabilidad diferente a CVE-2010-2632. • http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/crypto/dist/ssh/Attic/sftp-glob.c#rev1.13.12.1 http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/crypto/dist/ssh/Attic/sftp.c#rev1.21.6.1 http://cxib.net/stuff/glob-0day.c http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2010-008.txt.asc http://securityreason.com/achievement_securityalert/89 http://securityreason.com/exploitalert/9223 http://securityreason.com/securityalert/8116 • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2011-0539
The key_certify function in usr.bin/ssh/key.c in OpenSSH 5.6 and 5.7, when generating legacy certificates using the -t command-line option in ssh-keygen, does not initialize the nonce field, which might allow remote attackers to obtain sensitive stack memory contents or make it easier to conduct hash collision attacks. La función key_certify en usr.bin/ssh/key.c en OpenSSH v5.6 y v5.7 al generar los certificados de herencia con la opción de línea de comandos -t en ssh-keygen, no se inicializa el campo nonce, que podría permitir a atacantes remotos obtener contenido sensible de la pila de memoria o que sea más fácil de llevar a cabo ataques de colisión hash. • http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02794777 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10673 http://secunia.com/advisories/43181 http://secunia.com/advisories/44269 http://www.openssh.com/txt/legacy-cert.adv http://www.openwall.com/lists/oss-security/2011/02/04/2 http://www.securityfocus.com/bid/46155 http://www.securitytracker.com/id?1025028 http://www.vupen.com/english/advisories/2011/0284 https://exchange.xforce.ibmcloud. • CWE-264: Permissions, Privileges, and Access Controls •
