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 •

lib/gnutls_pk.c in libgnutls in GnuTLS 2.5.0 through 2.6.5 generates RSA keys stored in DSA structures, instead of the intended DSA keys, which might allow remote attackers to spoof signatures on certificates or have unspecified other impact by leveraging an invalid DSA key. lib/gnutls_pk.c en libgnutls en GnuTLS v2.5.0 hasta v2.6.5 genera claves RSA almacenados en estructuras DSA, en lugar de las claves DSA previstas, lo cual podría permitir a atacantes remotos suplantar firmas en los certificados o tener otro impacto no especificado por el utilizamiento de una clave DSA no es válida. • https://www.exploit-db.com/exploits/32965 http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3516 http://lists.gnu.org/archive/html/help-gnutls/2009-04/msg00018.html http://secunia.com/advisories/34842 http://secunia.com/advisories/35211 http://security.gentoo.org/glsa/glsa-200905-04.xml http://www.mandriva.com/security/advisories?name=MDVSA-2009:116 http://www.securityfocus.com/bid/34783 http://www.securitytracker.com/id?1022158 http://www.vupen.com/english • CWE-310: Cryptographic Issues •
