Integer overflow in the ffs_mountfs function in FreeBSD 6.1 allows local users to cause a denial of service (panic) and possibly execute arbitrary code via a crafted UFS filesystem that causes invalid or large size parameters to be provided to the kmem_alloc function. NOTE: a third party states that this issue does not cross privilege boundaries in FreeBSD because only root may mount a filesystem. Desbordamiento de enteros en la función ffs_mountfs en FreeBSD 6.1 permite a un usuario local provocar denegación de servicio (panico) y posiblemente ejecutar código a través de un sitema de ficheros UFS manipulado que provoca parámetros inválidos o de gran tamaño para proveer la función kmem_alloc. NOTA: Una tercera parte indica que este asunto no pasa los limites de privilegio en FreeBSD ya que solo el root podría montar un sistema de archivos. • http://docs.info.apple.com/article.html?artnum=305214 http://lists.apple.com/archives/security-announce/2007/Mar/msg00002.html http://lists.freebsd.org/pipermail/freebsd-security/2007-January/004218.html http://projects.info-pull.com/mokb/MOKB-03-11-2006.html http://secunia.com/advisories/22736 http://secunia.com/advisories/24479 http://www.kb.cert.org/vuls/id/552136 http://www.securityfocus.com/bid/20918 http://www.securitytracker.com/id?1017751 http://www.us-cert.gov& • CWE-189: Numeric Errors •

The kernel in FreeBSD 6.1 and OpenBSD 4.0 allows local users to cause a denial of service via unspecified vectors involving certain ioctl requests to /dev/crypto. El núcleo en FreeBSD 6.1 y OpenBSD 4.0 permite a usuarios locales provocar una denegación de servicio mediante vectores sin especificar relativas a peticiones concretas ioctl al /dev/crypto. • https://www.exploit-db.com/exploits/2639 http://elegerov.blogspot.com/2006/10/here-is-lame-proof-of-concept-code-for.html http://secunia.com/advisories/22543 http://www.securityfocus.com/bid/20713 •

ufs_vnops.c in FreeBSD 6.1 allows local users to cause an unspecified denial of service by calling the ftruncate function on a file type that is not VREG, VLNK or VDIR, which is not defined in POSIX. ufs_vnops.c en FreeBSD 6.1 permite a usuarios locales provocar una denegación de servicio llamando a la función ftruncate en un archivo que no es del tipo VREG, VLNK ni VDIR, el cual no está definido en POSIX. Month of Apple Bugs - This is a specially crafted HFS+ filesystem in a DMG image that can cause the do_hfs_truncate() function to panic the kernel (denial of service), when attempting to remove a file from the mounted filesystem. This issue can't lead to arbitrary code execution, although there's a significant risk of local HFS+ filesystems corruption. • https://www.exploit-db.com/exploits/2541 http://lists.freebsd.org/pipermail/cvs-src/2006-May/064488.html http://secunia.com/advisories/22413 http://www.securityfocus.com/bid/20522 •

p1003_1b.c in FreeBSD 6.1 allows local users to cause an unspecified denial of service by setting a scheduler policy, which should only be settable by root. p1003_1b.c en FreeBSD 6.1 permite a usuarios locales provocar una denegación de servicio no especificada estableciendo una política de tareas, lo cual sólo debe ser configurable por el usuario root. • https://www.exploit-db.com/exploits/2542 http://lists.freebsd.org/pipermail/cvs-src/2006-May/063969.html http://secunia.com/advisories/22413 http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/posix4/p1003_1b.c.diff?r1=1.24&r2=1.24.2.1 http://www.securityfocus.com/bid/20517 •

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&# •
