CVE-2008-6123 – net-snmp: incorrect application of hosts access restrictions in hosts.{allow,deny}
https://notcve.org/view.php?id=CVE-2008-6123
The netsnmp_udp_fmtaddr function (snmplib/snmpUDPDomain.c) in net-snmp 5.0.9 through 5.4.2.1, when using TCP wrappers for client authorization, does not properly parse hosts.allow rules, which allows remote attackers to bypass intended access restrictions and execute SNMP queries, related to "source/destination IP address confusion." La función netsnmp_udp_fmtaddr (snmplib/snmpUDPDomain.c) en net-snmp v5.0.9 hasta v5.4.2, cuando usando TCP wrappers para autorización de clientes, no analiza apropiadamente reglas hosts.allow, lo que permite a los atacantes remotos evitar restricciones de accesos intencionados y ejecuta consultas SNMP, relativas a "direcciones IP fuente/destino confusas". • http://bugs.gentoo.org/show_bug.cgi?id=250429 http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2009-07/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00003.html http://net-snmp.svn.sourceforge.net/viewvc/net-snmp/trunk/net-snmp/snmplib/snmpUDPDomain.c?r1=17325&r2=17367&pathrev=17367 http://net-snmp.svn.sourceforge.net/viewvc/net-snmp?view=rev&revision=17367 http://secunia.com/adviso • CWE-863: Incorrect Authorization •
CVE-2008-4989 – gnutls: certificate chain verification flaw
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 •
