CVE-2019-13164

Priority
Description
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.
Ubuntu-Description
Riccardo Schirone discovered that the QEMU bridge helper did not
properly validate network interface names. A local attacker could
possibly use this to bypass ACL restrictions.
