This issue is about a heap buffer over-read in flow.c, which could lead to access to an unmapped region of memory. This could result in crashing the software, memory modification, or possible remote execution.

For Debian 10 buster, this problem has been fixed in version 2.10.7+ds1-0+deb10u2.

We recommend that you upgrade your openvswitch packages.

For the detailed security status of openvswitch please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
