https://notcve.org/view.php?id=CVE-2017-5850
httpd in OpenBSD allows remote attackers to cause a denial of service (memory consumption) via a series of requests for a large file using an HTTP Range header. httpd en OpenBSD permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) a través de una serie de peticiones para un archivo grande utilizando un encabezado HTTP Range. OpenBSD HTTP server versions up to 6.0 suffer from a denial of service vulnerability. • https://www.exploit-db.com/exploits/41278 http://marc.info/?l=openbsd-cvs&m=148587359420912&w=2 http://packetstormsecurity.com/files/140944/OpenBSD-HTTP-Server-6.0-Denial-Of-Service.html http://seclists.org/fulldisclosure/2017/Feb/15 http://www.openwall.com/lists/oss-security/2017/02/02/6 http://www.securityfocus.com/bid/95997 http://www.securitytracker.com/id/1037758 https://ftp.openbsd.org/pub/OpenBSD/patches/5.9/common/034_httpd.patch.sig https://ftp.openbsd.or • CWE-770: Allocation of Resources Without Limits or Throttling •

The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets. La pila de TCP en 4.3BSD Net/2, utilizado en FreeBSD 5.4, NetBSD posiblemente 2.0, y OpenBSD posiblemente 3.6, no implementa correctamente el temporizador de la sesión, lo que permite a atacantes remotos causar una denegación de servicio (consumo de recursos) a través de paquetes manipulados. • http://jvn.jp/en/jp/JVN07930208/index.html http://jvndb.jvn.jp/jvndb/JVNDB-2014-000134 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195243 • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2011-3336
regcomp in the BSD implementation of libc is vulnerable to denial of service due to stack exhaustion. regcomp en la implementación BSD de libc, es vulnerable a una denegación de servicio debido al agotamiento de la pila. Mac OS X, Safari, Firefox and Kaspersky all suffer from a regular expression denial of service condition that was discovered long ago in regcomp(). • https://www.exploit-db.com/exploits/36288 http://seclists.org/fulldisclosure/2014/Mar/166 http://www.securityfocus.com/bid/50541 https://cxsecurity.com/issue/WLB-2011110082 https://www.securityfocus.com/archive/1/520390 • CWE-400: Uncontrolled Resource Consumption •
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 •

Multiple integer overflows in the glob implementation in libc in OpenBSD before 4.9 might allow context-dependent attackers to have an unspecified impact via a crafted string, related to the GLOB_APPEND and GLOB_DOOFFS flags, a different issue than CVE-2011-0418. Múltiples desbordamientos de entero en la implementación de glob en libc en OpenBSD anterior a v4.9 podría permitir a atacantes dependientes de contexto tener un impacto no especificado a través de una cadena manipulada, relacionado con el GLOB_APPEND y banderas GLOB_DOOFFS, una fallo diferente de CVE-2011-0418. • http://securityreason.com/achievement_securityalert/97 http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/glob.c#rev1.35 http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/glob.c.diff?r1=1.34%3Br2=1.35%3Bf=h http://www.securityfocus.com/bid/48004 • CWE-189: Numeric Errors •
