NVD Description

Note: Versions mentioned in the description apply only to the upstream tigervnc-icons package and not the tigervnc-icons package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A flaw was found in X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can trigger a heap buffer overflow condition, which may lead to an application crash or remote code execution in SSH X11 forwarding environments.
