Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-03-02 17:16:24 UTC
"qemu-bridge-helper.c in QEMU 4.0.0 does not ensure that a network interface name (obtained from bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass."
