Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. El kernel de Linux en versiones 4.9 y siguientes pueden forzarse a realizar llamadas muy caras a tcp_collapse_ofo_queue() y tcp_prune_ofo_queue() para cada paquete entrante, lo que puede conducir a una denegación de servicio. A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20181031-02-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/104976 http://www.securitytracker.com/id/1041424 http://www.securitytracker.com/id/1041434 https://access.redhat.co • CWE-400: Uncontrolled Resource Consumption •

An issue was discovered in the Cisco WebEx Extension before 1.0.7 on Google Chrome, the ActiveTouch General Plugin Container before 106 on Mozilla Firefox, the GpcContainer Class ActiveX control plugin before 10031.6.2017.0126 on Internet Explorer, and the Download Manager ActiveX control plugin before 2.1.0.10 on Internet Explorer. A vulnerability in these Cisco WebEx browser extensions could allow an unauthenticated, remote attacker to execute arbitrary code with the privileges of the affected browser on an affected system. This vulnerability affects the browser extensions for Cisco WebEx Meetings Server and Cisco WebEx Centers (Meeting Center, Event Center, Training Center, and Support Center) when they are running on Microsoft Windows. The vulnerability is a design defect in an application programing interface (API) response parser within the extension. An attacker that can convince an affected user to visit an attacker-controlled web page or follow an attacker-supplied link with an affected browser could exploit the vulnerability. • http://www.securityfocus.com/bid/95737 http://www.securitytracker.com/id/1037680 https://0patch.blogspot.com/2017/01/micropatching-remote-code-execution-in.html https://blog.filippo.io/webex-extension-vulnerability https://bugs.chromium.org/p/project-zero/issues/detail?id=1096 https://bugs.chromium.org/p/project-zero/issues/detail?id=1100 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170124-webex https://www.kb.cert.org/vuls/id/909240 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
