CVE-2017-18017 – kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c
https://notcve.org/view.php?id=CVE-2017-18017
The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. La función tcpmss_mangle_packet en net/netfilter/xt_TCPMSS.c en el kernel de Linux, en versiones anteriores a la 4.11 y en versiones 4.9.x anteriores a la 4.9.36, permite que atacantes remotos provoquen una denegación de servicio (uso de memoria previamente liberada y corrupción de memoria) o, posiblemente, otro tipo de impacto sin especificar aprovechando la presencia de xt_TCPMSS en una acción iptables. The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2638fd0f92d4397884fd991d8f4925cb3f081901 http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00047.html http://lists.opensuse.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •
CVE-2016-7797 – pacemaker: pacemaker remote nodes vulnerable to hijacking, resulting in a DoS attack
https://notcve.org/view.php?id=CVE-2016-7797
Pacemaker before 1.1.15, when using pacemaker remote, might allow remote attackers to cause a denial of service (node disconnection) via an unauthenticated connection. Pacemaker en versiones anteriores a 1.1.15, al usar el control remoto de marcapasos, podría permitir a atacantes remotos provocar una denegación de servicio (desconexión de nodo) a través de una conexión no autenticada. It was found that the connection between a pacemaker cluster and a pacemaker_remote node could be shut down using a new unauthenticated connection. A remote attacker could use this flaw to cause a denial of service. • http://bugs.clusterlabs.org/show_bug.cgi?id=5269 http://lists.opensuse.org/opensuse-security-announce/2016-11/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00001.html http://lists.opensuse.org/opensuse-updates/2016-12/msg00077.html http://rhn.redhat.com/errata/RHSA-2016-2578.html http://www.openwall.com/lists/oss-security/2016/10/01/1 http://www.securityfocus.com/bid/93261 https://github.com/ClusterLabs/pacemaker/commit/5ec24a2642bd0854b884d1a9b51d12371373b410 htt • CWE-254: 7PK - Security Features •
CVE-2015-1867 – pacemaker: acl read-only access allow role assignment
https://notcve.org/view.php?id=CVE-2015-1867
Pacemaker before 1.1.13 does not properly evaluate added nodes, which allows remote read-only users to gain privileges via an acl command. Vulnerabilidad en Pacemaker en versiones anteriores a 1.1.13, no evalúa correctamente nodos añadidos, lo que permite a usuarios remotos de sólo lectura obtener privilegios a través de un comando de acl. A flaw was found in the way pacemaker, a cluster resource manager, evaluated added nodes in certain situations. A user with read-only access could potentially assign any other existing roles to themselves and then add privileges to other users as well. • http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170610.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169671.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169995.html http://rhn.redhat.com/errata/RHSA-2015-1424.html http://rhn.redhat.com/errata/RHSA-2015-2383.html http://www.securityfocus.com/bid/74231 https://bugzilla.redhat.com/show_bug.cgi?id=1211370 https://github.com/ClusterLabs/pacemaker/commit/84ac07c https: • CWE-264: Permissions, Privileges, and Access Controls CWE-863: Incorrect Authorization •
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 •
CVE-2015-1848 – pcs: improper web session variable signing

The pcs daemon (pcsd) in PCS 0.9.137 and earlier does not set the secure flag for a cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session. NOTE: this issue was SPLIT per ADT2 due to different vulnerability types. CVE-2015-3983 is for the issue with not setting the HTTPOnly flag. El demonio pcs (pcsd) en PCS 0.9.137 y anteriores no establece el indicador de seguridad en una cookie de sesión https, lo cual hace más fácil a atacantes remotos capturar dicha cookie interceptando la transmisión dentro de una sesión http.
