https://notcve.org/view.php?id=CVE-2011-4122
Directory traversal vulnerability in openpam_configure.c in OpenPAM before r478 on FreeBSD 8.1 allows local users to load arbitrary DSOs and gain privileges via a .. (dot dot) in the service_name argument to the pam_start function, as demonstrated by a .. in the -c option to kcheckpass. Una vulnerabilidad de salto de directorio en el archivo openpam_configure.c en OpenPAM anterior a versión r478 en FreeBSD versión 8.1, permite a los usuarios locales cargar DSO arbitrarios y alcanzar privilegios por medio de un ..

CVE-2011-4062 – FreeBSD - UIPC socket heap Overflow (PoC)
https://notcve.org/view.php?id=CVE-2011-4062
Buffer overflow in the kernel in FreeBSD 7.3 through 9.0-RC1 allows local users to cause a denial of service (panic) or possibly gain privileges via a bind system call with a long pathname for a UNIX socket. Desbordamiento de búfer en la "emulación de Linux" de apoyo en FreeBSD v7.3 y v7.4, v8.1 y v8.2, y v9 antes de v9.0-RC1 permite a usuarios locales provocar una denegación de servicio (pánico) y posiblemente ejecutar código arbitrario mediante una llamada al llamado sistema de vinculación con un largo camino para un socket UNIX-domain, que no se manipula correctamente, cuando la dirección es utilizada por otras llamadas al sistema no especificado. • https://www.exploit-db.com/exploits/17908 http://secunia.com/advisories/46202 http://secunia.com/advisories/46564 http://security.freebsd.org/advisories/FreeBSD-SA-11:05.unix.asc http://security.freebsd.org/patches/SA-11:05/unix2.patch http://www.debian.org/security/2011/dsa-2325 http://www.exploit-db.com/exploits/17908 http://www.osvdb.org/75788 http://www.securityfocus.com/bid/49862 http://www.securitytracker.com/id?1026106 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2011-2895 – BSD compress LZW decoder buffer overflow
https://notcve.org/view.php?id=CVE-2011-2895
The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896. El descompresor en LZW en (1) la función BufCompressedFill en fontfile/decompress.c en X.Org libXfont antes de la versión v1.4.4 y (2) compress/compress.c en 4.3BSD, tal y como se utiliza en zopen.c en OpenBSD antes de la versión v3.8, FreeBSD, NetBSD, FreeType v2.1.9, y otros productos, no controla correctamente las palabras de código ausentes de la tabla de descompresión, lo que permite provocar un bucle infinito o un desbordamiento de búfer basado en memoria dinámica (heap) a atacantes (dependiendo del contexto) y posiblemente ejecutar código de su elección a través de un flujo comprimido debidamente modificado. Se trata de un problema relacionado con los CVE-2006-1168 y CVE-2011 2896. • http://cgit.freedesktop.org/xorg/lib/libXfont/commit/?id=d11ee5886e9d9ec610051a206b135a4cdc1e09a0 http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2011-007.txt.asc http://lists.apple.com/archives/security-announce/2012/Feb/msg00000.html http://lists.apple.com/archives/security-announce/2012/May/msg00001.html http://lists.apple.com/archives/security-announce/2015/Dec/msg00000.html http://lists.apple.com/archives/security-announce/2015/Dec/msg00001.html http://lists.apple.com/archives/secur • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
