A flaw was found in HTTP/2. Using PING frames and queuing of response PING ACK frames, a flood attack could occur resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...

HTTP/2: flood using HEADERS frames results in unbounded memory growth

A flaw was found in HTTP/2. Using HEADER frames with invalid HTTP headers and queuing of response RSTSTREAM frames, an attacker could cause a flood resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...

CVE-2019-17340

A flaw was found in xen. When the code processing grant table transfer requests finds a page with an address too large to be represented in the interface with the guest, it allocates a replacement page and copies page contents. The page as well as certain other remnants of an affected guest will ...

CVE-2019-18425

A flaw was in Xen. Guest specified limits for descriptor table access, during PV guest operations, were found to not be enforced. An attacker with the ability to emulate 32-bit guest user mode calls through call gates, would be allowed to install and then use descriptors of their choice as long a...

CVE-2019-18836

A flaw was found in envoy. When listeners are configured with continueonlistenerfilterstimeout true, an infinite busy loop is created if at least one connection is maintained on the loop. A remote attacker only needs to maintain one idle connection to consume one CPU core of the Envoy server,...

Siemens Simatic Uncontrolled Resource Consumption

A vulnerability has been identified in SIMATIC S7-1200 All versions, SIMATIC S7-1500 All Versions V2.6. An attacker could exhaust the available connection pool of an affected device by opening a sufficient number of connections to the device. Successful exploitation requires an attacker to be abl...

CVE-2019-15212

A use-after-free flaw was found in the RIO500 driver in the Linux kernel. The implementation of the driver did not consider that multiple RIO500 devices could be attached to the same system, simultaneously. When a second device connects, the system overwrites the data structures in use by the fir...

patch: do_ed_script in pch.c does not block strings beginning with a ! character

A flaw was found in GNU patch through version 2.7.6. Strings beginning with a exclamation mark are not blocked by default. When ed receives an exclamation mark-prefixed command line argument, the argument is executed as a shell command. The highest threat from this vulnerability is to data...

kernel: memory leak in genl_register_family() in net/netlink/genetlink.c

A flaw was found in the genlregisterfamily function in the Linux kernel. An attacker able to induce the error conditions could use this flaw to crash the system. The highest threat from this vulnerability is to system availability...

CVE-2019-18424

A flaw was found in Xen. A PCI device assigned to an untrusted domain can be programmed to an arbitrary address in DMA. When the guest domain is removed, the device is assigned back to dom0 allowing any in-flight DMA to potentially target critical host data. The highest threat from this...

CVE-2019-18421

A flaw was found in xen. Several race conditions exist that, if triggered, can cause Xen to drop or retain extra type counts allowing guests to get write access to in-use pagetables. The highest threat from this vulnerability is to data confidentiality and integrity as well as to system...
