Integer overflow in the systrace_preprepl function (STRIOCREPLACE) in systrace in OpenBSD 3.9 and NetBSD 3 allows local users to cause a denial of service (crash), gain privileges, or read arbitrary kernel memory via large numeric arguments to the systrace ioctl. Desbordamiento de entero en la función systrace_preprepl (STRIOCREPLACE) en systrace de OpenBSD 3.9 y NetBSD 3 permite a usuarios locales provocar una denegación de servicio (caída), escalar privilegios, o leer memoria del núcleo de su elección mediante argumentos numéricos muy grandes en la llamada ioctl systrace. • http://openbsd.org/errata.html#systrace http://scary.beasts.org/security/CESA-2006-003.html http://secunia.com/advisories/22324 http://securitytracker.com/id?1017009 http://www.osvdb.org/29570 http://www.securityfocus.com/bid/20392 https://exchange.xforce.ibmcloud.com/vulnerabilities/29392 •

Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service (panic), obtain sensitive information, and possibly execute arbitrary code via crafted Link Control Protocol (LCP) packets with an option length that exceeds the overall length, which triggers the overflow in (1) pppoe and (2) ippp. NOTE: this issue was originally incorrectly reported for the ppp driver. Desbordamiento de búfer en el controlador sppp en FreeBSD 4.11 hasta 6.1, NetBSD 2.0 hasta 4.0 beta anterior al 23/08/2006, y OpenBSD 3.8 y 3.9 anterior al 02/09/2006 permite a atacanets remotos provocar una denegación de servicio (panic), obtener información sensible, y posiblemente ejecutar código de su elección mediante paquetes LCP (Link Control Protocol) modificados con una longitud de opciones que excede la longitud total, lo que provoca un desbordamiento en (1) pppoe y (2) ippp. NOTA: este problema fue inicial e incorrectamente reportado para el controlador ppp. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2006-019.txt.asc http://secunia.com/advisories/21587 http://secunia.com/advisories/21731 http://security.FreeBSD.org/advisories/FreeBSD-SA-06:18.ppp.asc http://security.FreeBSD.org/patches/SA-06:18/ppp4x.patch http://securitytracker.com/id?1016745 http://www.openbsd.org/errata.html#sppp http://www.openbsd.org/errata38.html#sppp http://www.securityfocus.com/bid/19684 https://exchange.xforce.ibmcloud.com/vulnerabilities&# •

The securelevels implementation in FreeBSD 7.0 and earlier, OpenBSD up to 3.8, DragonFly up to 1.2, and Linux up to 2.6.15 allows root users to bypass immutable settings for files by mounting another filesystem that masks the immutable files while the system is running. • http://archives.neohapsis.com/archives/openbsd/2005-10/1523.html http://lists.grok.org.uk/pipermail/full-disclosure/2006-January/041177.html http://www.redteam-pentesting.de/advisories/rt-sa-2005-015.txt http://www.redteam-pentesting.de/advisories/rt-sa-2005-15.txt https://exchange.xforce.ibmcloud.com/vulnerabilities/24037 •

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:/& •

The TCP stack (tcp_input.c) in OpenBSD 3.5 and 3.6 allows remote attackers to cause a denial of service (system panic) via crafted values in the TCP timestamp option, which causes invalid arguments to be used when calculating the retransmit timeout. • http://secunia.com/advisories/13819 http://securitytracker.com/id?1012861 http://www.openbsd.org/errata35.html http://www.securityfocus.com/bid/12250 •
