https://notcve.org/view.php?id=CVE-2012-4561
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. •
CVE-2012-4559
https://notcve.org/view.php?id=CVE-2012-4559
Multiple double free vulnerabilities in the (1) agent_sign_data function in agent.c, (2) channel_request function in channels.c, (3) ssh_userauth_pubkey function in auth.c, (4) sftp_parse_attr_3 function in sftp.c, and (5) try_publickey_from_file function in keyfiles.c in libssh before 0.5.3 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors. Múltiples vulnerabilidades de doble liberación en las funciones (1) agent_sign_data en agent.c, (2) channel_request en channels.c, (3) ssh_userauth_pubkey en auth.c, (4) sftp_parse_attr_3 en sftp.c, y (5) try_publickey_from_file en keyfiles.c en libssh antes de v0.5.3 permiten a atacantes remotos provocar una denegación de servicio (caída de la aplicación) y posiblemente ejecutar código de su elección 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. • CWE-399: Resource Management Errors •
CVE-2012-4562
https://notcve.org/view.php?id=CVE-2012-4562
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 •
