CVE-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 •
