Memory Corruption was discovered in the cmsgpack library in the Lua subsystem in Redis before 3.2.12, 4.x before 4.0.10, and 5.x before 5.0 RC2 because of stack-based buffer overflows.

An Integer Overflow issue was discovered in the struct library in the Lua subsystem in Redis before 3.2.12, 4.x before 4.0.10, and 5.x before 5.0 RC2, leading to a failure of bounds checking.

Ansible before versions 2.1.6.0, 2.2.3.0, 2.3.1.0, and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.

A potential integer overflow issue was found in the networking back-end of QEMU. It could occur while receiving packets, because it accepted packets with large size value. Such overflow could lead to OOB buffer access issue. A user inside guest could use this flaw to crash the QEMU process resulting in DoS.

A vulnerability in openvswitch was found. While parsing an OFPTQUEUEGETCONFIGREPLY type OFP 1.0 message, there is a buffer over-read that is caused by an unsigned integer underflow in the function ofputilpullqueuegetconfigreply10 in lib/ofp-util.c.
