Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-12-20 21:45:50 UTC
"Multiple versions of Open vSwitch are vulnerable to crafted LLDP
packets causing denial of service, and data underflow attacks.
Triggering the vulnerabilities requires LLDP processing to be enabled
for a specific port.  Open vSwitch versions prior to 2.4.0 are not
vulnerable.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
did not assign the identifier to this issue yet.  The identifier will
be communicated separately.  This issue does not affect the `lldpd'
project, although they share a code base.  The issue is related to
parsing the Auto Attach TLVs, which is specific to the Open vSwitch
implementation."

Please bump to 2.15.7, 2.17.5.
