Description Sam James archtester gentoo-dev Security 2021-01-13 19:40:46 UTC
"Multiple versions of Open vSwitch are vulnerable to denial of service
attacks in which crafted LLDP packets could cause memory to be lost
when allocating data to handle specific optional TLVs.  Triggering the
vulnerability requires LLDP processing to be enabled for a specific
port.  Open vSwitch versions before 2.5.x are not vulnerable.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
previously assigned the identifier CVE-2020-27827 to this issue for
the `lldpd` project, and the Open vSwitch project."
