OpenBSD 4.2 allows local users to cause a denial of service (kernel panic) by calling the SIOCGIFRTLABEL IOCTL on an interface that does not have a route label, which triggers a NULL pointer dereference when the return value from the rtlabel_id2name function is not checked. OpenBSD 4.2 permtie a usuarios locales provocar denegación de servicio (kernel panic) a través de una llamada SIOCGIFRTLABEL IOCTL sobre una interfaz que no tiene una etiqueta route, el cual dispara un puntero de referencia NULL cuando devuelve el valor de la función rtlabel_id2name no está validada. • https://www.exploit-db.com/exploits/4935 http://marc.info/?l=openbsd-security-announce&m=120007327504064 http://secunia.com/advisories/28473 http://www.openbsd.org/errata42.html#005_ifrtlabel http://www.securityfocus.com/bid/27252 http://www.securitytracker.com/id?1019188 •

Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU. Un desbordamiento de búfer en la región stack de la memoria en la función cons_options en el archivo options.c en dhcpd en OpenBSD versiones 4.0 hasta 4.2, y algunas otras implementaciones de dhcpd basadas en ISC dhcp-2, permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (bloqueo del demonio) por medio de una petición DHCP que especifica un tamaño máximo de mensaje más pequeño que el IP MTU mínimo. • https://www.exploit-db.com/exploits/4601 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=446354 http://secunia.com/advisories/27160 http://secunia.com/advisories/27273 http://secunia.com/advisories/27338 http://secunia.com/advisories/27350 http://secunia.com/advisories/32668 http://securitytracker.com/id?1021157 http://sunsolve.sun.com/search/document.do?assetkey=1-21-109077-21-1 http://sunsolve.sun.com/search/document.do?assetkey=1-26-243806-1 http://www.coresecurity&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. • https://www.exploit-db.com/exploits/1008 ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:15.tcp.asc ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.64/SCOSA-2005.64.txt http://secunia.com/advisories/15393 http://secunia.com/advisories/15417 http://secunia.com/advisories/18222 http://secunia.com/advisories/18662 http://support.avaya.com/elmodocs2/security/ASA-2006-032.htm http://www.cisco.com/warp/public/707/cisco-sn-20050518-tcpts.shtml http:/& •

Format string vulnerability in wrapper.c in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16 allows remote attackers with CVSROOT commit access to cause a denial of service (application crash) and possibly execute arbitrary code via format string specifiers in a wrapper line. • https://www.exploit-db.com/exploits/24182 ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:14.cvs.asc http://lists.grok.org.uk/pipermail/full-disclosure/2004-June/022441.html http://security.e-matters.de/advisories/092004.html http://www.securityfocus.com/bid/10499 https://exchange.xforce.ibmcloud.com/vulnerabilities/16365 •
