Memory leak in the zlib_stateful_finish function in crypto/comp/c_zlib.c in OpenSSL 0.9.8l and earlier and 1.0.0 Beta through Beta 4 allows remote attackers to cause a denial of service (memory consumption) via vectors that trigger incorrect calls to the CRYPTO_cleanup_all_ex_data function, as demonstrated by use of SSLv3 and PHP with the Apache HTTP Server, a related issue to CVE-2008-1678. Fuga de memoria en la función zlib_stateful_finish en crypto/comp/c_zlib.c en OpenSSL v0.9.8l y anteriores, y v1.0.0 Beta a la Beta 4, permite a atacantes remoso provocar una denegación de servicio (consumo de memoria) a través de vectores que provocan llamadas incorrectas a la función CRYPTO_free_all_ex_data, como se demostró usando SSLv3 y PHP con el Apache HTTP Server, una cuestión relacionada con el CVE-2008-1678. • http://cvs.openssl.org/chngview?cn=19068 http://cvs.openssl.org/chngview?cn=19069 http://cvs.openssl.org/chngview?cn=19167 http://lists.fedoraproject.org/pipermail/package-announce/2010-April/038587.html http://lists.fedoraproject.org/pipermail/package-announce/2010-April/039561.html http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00009.html http://marc.info/?l=bugtraq&m=127128920008563&w=2 http://secunia.com/advisories/38175 http://secunia.com/advisories/38181 http: • CWE-399: Resource Management Errors CWE-401: Missing Release of Memory after Effective Lifetime •

The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. El protocolo TLS y el protocolo SSL v3.0 y posiblemente versiones anteriores, tal y como se usa en Microsoft Internet Information Services (IIS) v7.0, mod_ssl en el servidor HTTP Apache v2.2.14 y anteriores, OpenSSL antes de v0.9.8l, GnuTLS v2.8.5 y anteriores, Mozilla Network Security Services (NSS) v3.12.4 y anteriores, y otros productos, no asocia apropiadamente la renegociación del Handshake SSL en una conexión existente, lo que permite ataques man-in-the-middle en los que el atacante inserta datos en sesiones HTTPS, y posiblemente otro tipo de sesiones protegidas por SSL o TLS, enviando una petición de autenticación que es procesada retroactivamente por un servidor en un contexto post-renegociación. Se trata de un ataque de "inyección de texto plano", también conocido como el problema del "Proyecto Mogul". • https://www.exploit-db.com/exploits/10071 https://www.exploit-db.com/exploits/10579 http://archives.neohapsis.com/archives/bugtraq/2013-11/0120.html http://blog.g-sec.lu/2009/11/tls-sslv3-renegotiation-vulnerability.html http://blogs.iss.net/archive/sslmitmiscsrf.html http://blogs.sun.com/security/entry/vulnerability_in_tls_protocol_during http://clicky.me/tlsvuln http://extendedsubset.com/?p=8 http://extendedsubset.com/Renegotiating_TLS.pdf http://h20000.www2.hp.com/bizsuppo • CWE-295: Improper Certificate Validation CWE-300: Channel Accessible by Non-Endpoint •

OpenSSL before 0.9.8k on WIN64 and certain other platforms does not properly handle a malformed ASN.1 structure, which allows remote attackers to cause a denial of service (invalid memory access and application crash) by placing this structure in the public key of a certificate, as demonstrated by an RSA public key. OpenSSL anterior a v0.9.8k en plataformas WIN64 y otras plataformas no maneja adecuadamente una estructura ASN.1 malformada, permitiendo a atacantes remotos provocar una denegación de servicio (acceso de memoria inválido y caída de la aplicación) al poner esta estructura en la clave pública de un certificado, como la utilizada por una clave pública RSA. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2009-008.txt.asc http://lists.apple.com/archives/security-announce/2009/Sep/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2009-05/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-07/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2011-07/msg00014.html http://marc.info/?l=bugtraq&m=124464882609472&w=2 http://marc.info/?l=bugtraq&m=127678688104458&w=2 http://secu • CWE-189: Numeric Errors •
