CVSS: 9.3EPSS: 1%CPEs: 40EXPL: 0CVE-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 •

Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 20070403 and (2) freetype 2.3.2 and earlier allows remote authenticated users to execute arbitrary code via crafted BDF fonts, which result in a heap overflow.
