CVSS: 5.0EPSS: 0%CPEs: 56EXPL: 0CVE-2015-3281 – haproxy: information leak in buffer_slow_realign()
https://notcve.org/view.php?id=CVE-2015-3281
The buffer_slow_realign function in HAProxy 1.5.x before 1.5.14 and 1.6-dev does not properly realign a buffer that is used for pending outgoing data, which allows remote attackers to obtain sensitive information (uninitialized memory contents of previous requests) via a crafted request. La función buffer_slow_realign en HAProxy 1.5.x anterior a 1.5.14 y 1.6-dev no realinea correctamente un buffer que es utilizado para datos salientes pendientes, lo que permite a atacantes remotos obtener información sensible (contenidos de memoria no inicializada de solicitudes previas) a través de una solicitud manipulada. An implementation error related to the memory management of request and responses was found within HAProxy's buffer_slow_realign() function. An unauthenticated remote attacker could possibly use this flaw to leak certain memory buffer contents from a past request or session. • http://git.haproxy.org/?p=haproxy-1.5.git%3Ba=commit%3Bh=7ec765568883b2d4e5a2796adbeb492a22ec9bd4 http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00023.html http://rhn.redhat.com/errata/RHSA-2015-1741.html http://rhn.redhat.com/errata/RHSA-2015-2666.html http://www.debian.org/security/2015/dsa-3301 http://www.haproxy.org/news.html http://www.securityfocus.com/bid/75554 http://www.ubuntu.com& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 5.0EPSS: 5%CPEs: 8EXPL: 1CVE-2014-6269 – haproxy: remote client denial of service vulnerability
https://notcve.org/view.php?id=CVE-2014-6269
Multiple integer overflows in the http_request_forward_body function in proto_http.c in HAProxy 1.5-dev23 before 1.5.4 allow remote attackers to cause a denial of service (crash) via a large stream of data, which triggers a buffer overflow and an out-of-bounds read. Múltiples desbordamientos de enteros en la función http_request_forward_body en proto_http.c en HAProxy 1.5-dev23 anterior a 1.5.4 permiten a atacantes remotos causar una denegación de servicio (caída) a través de un flujo grande de datos, lo que provoca un desbordamiento de buffer y una lectura fuera de rango. A buffer overflow flaw was discovered in the way HAProxy handled, under very specific conditions, data uploaded from a client. A remote attacker could possibly use this flaw to crash HAProxy. • http://article.gmane.org/gmane.comp.web.haproxy/17726 http://article.gmane.org/gmane.comp.web.haproxy/18097 http://git.haproxy.org/?p=haproxy-1.5.git%3Ba=commitdiff%3Bh=b4d05093bc89f71377230228007e69a1434c1a0c http://rhn.redhat.com/errata/RHSA-2014-1292.html http://secunia.com/advisories/59936 http://secunia.com/advisories/61507 http://www.openwall.com/lists/oss-security/2014/09/09/23 https://access.redhat.com/security/cve/CVE-2014-6269 https://bugzilla.redhat.com/show_bug.cgi • CWE-189: Numeric Errors CWE-400: Uncontrolled Resource Consumption •

HAProxy 1.4 before 1.4.24 and 1.5 before 1.5-dev19, when configured to use hdr_ip or other "hdr_*" functions with a negative occurrence count, allows remote attackers to cause a denial of service (negative array index usage and crash) via an HTTP header with a certain number of values, related to the MAX_HDR_HISTORY variable. HAProxy 1.4 anteiror a 1.4.24 y 1.5 anteiror a 1.5-dev19, cuando es configurado para usar el hdr_ip u otras funciones "hdr_*" con una cuenta de ocurrencia negativa, permite a atacantes remotos provocar una denegación de servicio (uso de indexación negativa de array y caída) a través de una cabecera HTTP con un número determinado de valores.

https://notcve.org/view.php?id=CVE-2013-1912
Buffer overflow in HAProxy 1.4 through 1.4.22 and 1.5-dev through 1.5-dev17, when HTTP keep-alive is enabled, using HTTP keywords in TCP inspection rules, and running with rewrite rules that appends to requests, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted pipelined HTTP requests that prevent request realignment from occurring. Desbordamiento de búfer en HAProxy v1.4 y v1.5 mediante v1.5-dev17 través de 1.5-dev17 al mantenimiento de conexión está habilitado, mediante palabras clave HTTP en las reglas de inspección de TCP, y corriendo con las reglas con reescritura, que se anexan a las solicitudes, permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de peticiones pipeline HTTP diseñadas a medida que se produzca la realineación. • http://lists.fedoraproject.org/pipermail/package-announce/2013-April/103730.html http://lists.fedoraproject.org/pipermail/package-announce/2013-April/103770.html http://lists.fedoraproject.org/pipermail/package-announce/2013-April/103794.html http://rhn.redhat.com/errata/RHSA-2013-0729.html http://rhn.redhat.com/errata/RHSA-2013-0868.html http://secunia.com/advisories/52725 http://www.debian.org/security/2013/dsa-2711 http://www.openwall.com/lists/oss-security/2013/04/03/1 http:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
