RubyGems versions between 2.0.0 and 2.6.13 are vulnerable to a possible remote code execution vulnerability. YAML deserialization of gem specifications can bypass class white lists. Specially crafted serialized objects can possibly be used to escalate to remote code execution.

RubyGems vulnerable to Deserialization of Untrusted Data

Уязвимость сервера Qemu-NBD эмулятора аппаратного обеспечения QEMU, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость компонента io/channel-websock.c эмулятора аппаратного обеспечения QEMU, позволяющая нарушителю вызвать отказ в обслуживании

Qemu through 2.10.0 allows remote attackers to cause a memory leak by triggering slow data-channel read operations, related to io/channel-websock.c.

An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service.
