golang: math/big: panic during recursive division of very large numbers

A flaw was found in the math/big package of Go's standard library that causes a denial of service. Applications written in Go that use math/big via cryptographic packages, including crypto/rsa and crypto/x509, are vulnerable and can potentially cause panic via a crafted certificate chain. The...

CVE-2020-14339

A flaw was found in libvirt, where it leaked a file descriptor for /dev/mapper/control into the QEMU process. This file descriptor allows for privileged operations to happen against the device-mapper on the host. This flaw allows a malicious guest user or process to perform operations outside of...
