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.
