nsis

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2015-9267, CVE-2015-9268.

More information:

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.
