Description Tomas Hoger 2019-11-28 21:06:30 UTC

It was discovered that the FilePermission class in the Libraries component of OpenJDK did not properly validate paths during the default file system provider.  This could cause it to handle invalid paths as valid on certain platforms.

This issue is only known to affect OpenJDK on Microsoft Windows platform, Linux builds are not known to be affected.
