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 •

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 •
