Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- HTTP DoS An attacker performs flooding at the HTTP level to bring down only a particular web application rather than anything listening on a TCP/IP connection. This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.

NASL family SuSE Local Security Checks NASL id SUSE_SU-2017-1080-1.NASL description This update for xen fixes the following issues: These security issues were fixed : - CVE-2017-7228: Broken check in memory_exchange() permited PV guest breakout (bsc#1030442). - XSA-206: Unprivileged guests issuing writes to xenstore were able to stall progress of the control domain or driver domain, possibly leading to a Denial of Service (DoS) of the entire host (bsc#1030144). - CVE-2017-6505: The ohci_service_ed_list function in hw/usb/hcd-ohci.c allowed local guest OS users to cause a denial of service (infinite loop) via vectors involving the number of link endpoint list descriptors (bsc#1028235). - CVE-2017-6414: Memory leak in the vcard_apdu_new function in card_7816.c in libcacard allowed local guest OS users to cause a denial of service (host memory consumption) via vectors related to allocating a new APDU object (bsc#1027570). - CVE-2017-2633: The VNC display driver support was vulnerable to an out-of-bounds memory access issue. A user/process inside guest could use this flaw to cause DoS (bsc#1026636). - CVE-2016-9603: A privileged user within the guest VM can cause a heap overflow in the device model process, potentially escalating their privileges to that of the device model process (bsc#1028655). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory.
