Package : nsis
Version : 2.46-10+deb8u1
CVE ID : CVE-2015-9267 CVE-2015-9268

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.
