Description Alexander Bergmann 2021-01-25 09:19:25 UTC
CVE-2020-27827

Two vulnerabilities were discovered in the LLPD implementation of Open
vSwitch, a software-based Ethernet virtual switch, which could result in
denial of service.

For the stable distribution (buster), these problems have been fixed in
version 2.10.6+ds1-0+deb10u1.

We recommend that you upgrade your openvswitch packages.

For the detailed security status of openvswitch please refer to
its security tracker page at:
