"Among others, Andre Heinicke from gpg4win.org found several issues of
nsis, a tool for creating quick and user friendly installers for

Microsoft Windows operating systems.

The issues are fixed by ... ... using SetDefaultDllDirectories() to
restrict implicitly loaded and dynamically loaded modules to trusted
directories ... creating temporary directories in a way that only
elevated users can write into it ... not implicitly linking against
Version.dll but using wrapper functions

For Debian 8 'Jessie', these problems have been fixed in version
2.46-10+deb8u1.

We recommend that you upgrade your nsis packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
