https://notcve.org/view.php?id=CVE-2009-1415
lib/pk-libgcrypt.c in libgnutls in GnuTLS before 2.6.6 does not properly handle invalid DSA signatures, which allows remote attackers to cause a denial of service (application crash) and possibly have unspecified other impact via a malformed DSA key that triggers a (1) free of an uninitialized pointer or (2) double free. lib/pk-libgcrypt.c en libgnutls en GnuTLS anterior a v2.6.6 no maneja correctamente las firmas DSA, lo cual permite a atacantes remotos provocar una denegación de servicio (cuelgue de aplicación) y posiblemente tiene otro impacto no especificado a través de una clave DSA malformada que desencadena (1) una liberación del puntero no inicializado. (2) una doble liberación. • https://www.exploit-db.com/exploits/32964 http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3515 http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3502 http://secunia.com/advisories/34842 http://secunia.com/advisories/35211 http://security.gentoo.org/glsa/glsa-200905-04.xml http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3488 http://www.mandriva.com/security/advisories?name=MDVSA-2009:116 http://www.securityfocus.com/bid/34783 http:/& • CWE-824: Access of Uninitialized Pointer •

https://notcve.org/view.php?id=CVE-2008-4989
The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN). La función _gnutls_x509_verify_certificate en lib/x509/verify.c en libgnutls en GnuTLS antes de v2.6.1 confía en las cadenas de certificado en las que el último certificado es un certificado de confianza arbitraria, auto-firmado, lo que permite a atacantes de tipo "hombre en el medio" (man-in-the-middle) insertar un certificado falso para cualquier Distinguished Name(DN). • http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3215 http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3217 http://lists.opensuse.org/opensuse-security-announce/2008-12/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-04/msg00010.html http://secunia.com/advisories/32619 http://secunia.com/advisories/32681 http://secunia.com/advisories/32687 http://secunia.com/advisories/32879 http://secunia.com/advisories/33501 http://secunia.com/advi • CWE-295: Improper Certificate Validation •

Use-after-free vulnerability in the _gnutls_handshake_hash_buffers_clear function in lib/gnutls_handshake.c in libgnutls in GnuTLS 2.3.5 through 2.4.0 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via TLS transmission of data that is improperly used when the peer calls gnutls_handshake within a normal session, leading to attempted access to a deallocated libgcrypt handle. Vulnerabilidad de uso después de liberación en la función _gnutls_handshake_hash_buffers_clear de lib/gnutls_handshake.c en libgnutls de GnuTLS 2.3.5 hasta 2.4.0 permite a atacantes remotos provocar una denegación de servicio (caida) o posiblemente ejecutar código de su elección a través de transmisiones TLS de datos que no son usadas apropiadamente cuando las llamadas pares gnutls_handshake dentro de una sesión normal, conducen a intentos de acceso a manejadores libgcrypt no asignados. • http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2947 http://secunia.com/advisories/31505 http://www.gnu.org/software/gnutls/security.html http://www.nabble.com/Details-on-the-gnutls_handshake-local-crash-problem--GNUTLS-SA-2008-2--td18205022.html http://www.securityfocus.com/bid/30713 http://www.vupen.com/english/advisories/2008/2398 https://exchange.xforce.ibmcloud.com/vulnerabilities/44486 https://issues.rpath.com/browse/RPL-2650 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The _gnutls_recv_client_kx_message function in lib/gnutls_kx.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 continues to process Client Hello messages within a TLS message after one has already been processed, which allows remote attackers to cause a denial of service (NULL dereference and crash) via a TLS message containing multiple Client Hello messages, aka GNUTLS-SA-2008-1-2. La función _gnutls_recv_client_kx_message en lib/gnutls_kx.c de libgnutls en gnutls-serv de GnuTLS versiones anteriores a la 2.2.4 continúa procesando los mensajes Client Hello dentro de un mensaje TLS después de que uno ya haya sido procesado, lo cual permite a atacantes remotos provocar una denegación de servicio (referencia NULL y caída) a través de un mensaje TLS que contiene múltiples mensajes Hello Client, también conocida como GNUTLS-SA-2008-1-2. • http://git.savannah.gnu.org/gitweb/?p=gnutls.git%3Ba=commitdiff%3Bh=bc8102405fda11ea00ca3b42acc4f4bce9d6e97b http://lists.gnu.org/archive/html/gnutls-devel/2008-05/msg00051.html http://lists.gnu.org/archive/html/gnutls-devel/2008-05/msg00055.html http://lists.gnu.org/archive/html/gnutls-devel/2008-05/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2008-09/msg00003.html http://secunia.com/advisories/30287 http://secunia.com/advisories/30302 http://secunia.com/advisories/3 • CWE-287: Improper Authentication CWE-476: NULL Pointer Dereference •
