The ipfw firewall in FreeBSD 6.0-RELEASE allows remote attackers to cause a denial of service (firewall crash) via ICMP IP fragments that match a reset, reject or unreach action, which leads to an access of an uninitialized pointer. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:04.ipfw.asc http://secunia.com/advisories/18378 http://securitytracker.com/id?1015477 http://www.osvdb.org/22319 http://www.securityfocus.com/bid/16209 https://exchange.xforce.ibmcloud.com/vulnerabilities/24073 • CWE-824: Access of Uninitialized Pointer •

The ispell_op function in ee on FreeBSD 4.10 to 6.0 uses predictable filenames and does not confirm which file is being written, which allows local users to overwrite arbitrary files via a symlink attack when ee invokes ispell. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:02.ee.asc http://secunia.com/advisories/18404 http://securitytracker.com/id?1015469 http://www.osvdb.org/22320 http://www.securityfocus.com/bid/16207 https://exchange.xforce.ibmcloud.com/vulnerabilities/24074 •

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 •

The AES-XCBC-MAC algorithm in IPsec in FreeBSD 5.3 and 5.4, when used for authentication without other encryption, uses a constant key instead of the one that was assigned by the system administrator, which can allow remote attackers to spoof packets to establish an IPsec session. El algoritmo AES-XCBC-MACen IPsec en FreeBSD 5.3 y 5.4, cuando se usa para autentificación sin otra encriptación, usa una clave constante (en vez de la que asigne el administrador del sistema). Esto puede permitir que atacantes remotos establezcan una sesión IPsec. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:19.ipsec.asc http://secunia.com/advisories/16244 http://securitytracker.com/id?1014586 http://www.securityfocus.com/bid/14394 https://exchange.xforce.ibmcloud.com/vulnerabilities/21551 •

The device file system (devfs) in FreeBSD 5.x does not properly check parameters of the node type when creating a device node, which makes hidden devices available to attackers, who can then bypass restrictions on a jailed process. El sistema de ficheros de dispositivos en FreeBSD 5.x no comprueba adecuadamente los parámetros del tipo de nodo cuando crea un nodo de dispositivo, lo que hace que dispositivos ocultos estén disponibles a tacantes (quienes pueden por tanto sortear restricciones en ciertos procesos). • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:17.devfs.asc http://secunia.com/advisories/16145 http://securitytracker.com/id?1014536 http://www.osvdb.org/18123 http://www.securityfocus.com/bid/14334 https://exchange.xforce.ibmcloud.com/vulnerabilities/21451 •
