Integer signedness error in the i386_set_ldt call in FreeBSD 5.5, and possibly earlier versions down to 5.2, allows local users to cause a denial of service (crash) via unspecified arguments that use negative signed integers to cause the bzero function to be called with a large length parameter, a different vulnerability than CVE-2006-4172. Error de presencia de signo (signedness) de entero en la llamada i386_set_ldt en FreeBSD 5.5, y posiblemente versiones anteriores desde la 5.2, permite a usuarios locales provocar una denegación de servicio (caída) mediante argumentos no especificados que usan enteros con signo negativo para provocar la llamada a la función bzero con un parámetro de gran longitud, una vulnerabilidad diferente a CVE-2006-4172. • https://www.exploit-db.com/exploits/28648 http://secunia.com/advisories/22064 http://securitytracker.com/id?1016927 http://www.idefense.com/intelligence/vulnerabilities/display.php?id=415 http://www.securityfocus.com/archive/1/446946/100/0/threaded http://www.securityfocus.com/bid/20158 •

opiepasswd in One-Time Passwords in Everything (OPIE) in FreeBSD 4.10-RELEASE-p22 through 6.1-STABLE before 20060322 uses the getlogin function to determine the invoking user account, which might allow local users to configure OPIE access to the root account and possibly gain root privileges if a root shell is permitted by the configuration of the wheel group or sshd. 'opiepasswd' en One-Time Passwords en Everything (OPIE) en FreeBSDE 4.10-RELEASE-p22 a 6.1-STABLE anteriores a 20060322 usa la función "getlogin" para determinar la cuenta de usuario invocante, lo que podría permitir a usuarios locales para configurar acceso de OPIE a la cuenta 'root' y posiblemente ganar privilegios de root si un intérprete de comandos de root es permitido por la configuración del grupo 'wheel' o sshd. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:12.opie.asc http://secunia.com/advisories/19347 http://securitytracker.com/id?1015817 http://www.osvdb.org/24067 http://www.securityfocus.com/bid/17194 http://www.vupen.com/english/advisories/2006/1074 https://exchange.xforce.ibmcloud.com/vulnerabilities/25397 •

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:/& •

Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses. • ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.24/SCOSA-2005.24.txt http://marc.info/?l=freebsd-hackers&m=110994026421858&w=2 http://marc.info/?l=freebsd-security&m=110994370429609&w=2 http://marc.info/?l=openbsd-misc&m=110995101417256&w=2 http://secunia.com/advisories/15348 http://secunia.com/advisories/18165 http://securitytracker.com/id?1013967 http://sunsolve.sun.com/search/document.do? •
