Subject: [mapserver-announce] security release available: MapServer 8.6.1
Message-ID: <5d125ef9-78d5-4eb0-9a12-8f7a5a3eb87b@gatewaygeomatics.com>

The MapServer team announces the immediate availability of security 
release of 8.6.1

This release contains a fix for a security flaw in the SLD parser. See 
the changelog for the list of changes ( 
https://mapserver.org/development/changelog/changelog-8-6.html#changelog-8-6-1 
). You may also review this specific Security Advisory ( 
https://github.com/MapServer/MapServer/security/advisories/GHSA-cv4m-mr84-fgjp 
) as well as MapServer?s Security Policy ( 
https://github.com/MapServer/MapServer/blob/main/SECURITY.md ). Please 
note: as security support for the 7.6 branch has ended, and branches 
8.4, 8.2 & 8.0 are not supported, all users are strongly encouraged to 
upgrade to the MapServer 8.6.1 release.

Here is the direct download for today's release:

  - tar.gz: https://download.osgeo.org/mapserver/mapserver-8.6.1.tar.gz
  - zip: https://download.osgeo.org/mapserver/mapserver-8.6.1.zip

Thanks,
