More information:

Among others, Andre Heinicke from 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.
