Debian 10 DLA-3168-1 Critical: Openvswitch Buffer Over-Read

An issue has been found in openvswitch, a software-based, Ethernet
virtual switch.

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.
