Description:
Martin Lemburg has reported a security issue in Tcl, which potentially can be exploited by malicious, local users to gain escalated privileges.
The security issue is caused due to a boundary error within tcl/win/tclWinReg.c when processing overly long registry key names. This can be exploited to cause a buffer overflow by e.g. creating a malicious registry key and enticing another user to query it with an application using Tcl.
The security issue is reported in versions prior to 8.4.15. Other versions may also be affected.
Solution:
Update to version 8.4.15.
