Description Tomas Hoger 2020-11-18 21:42:10 UTC
A flaw was found in the way MariaDB and MySQL set permissions for named pipes when running on the Microsoft Windows platform.  A local attacker could use this flaw to perform a man-in-the-middle attack against local client to server connections over the named pipes.  Note that this issue did not affect MariaDB or MySQL running on Linux.

MariaDB upstream bug and fix:

https://jira.mariadb.org/browse/MDEV-24040
https://github.com/MariaDB/server/commit/3829b408d6

Comment 1 Tomas Hoger 2020-11-18 21:46:39 UTC
Statement:

This issue did not affect any version of MariaDB or MySQL as included in Red Hat products, as it only affected the versions of MariaDB or MySQL running on the Microsoft Windows platform.
