Description:
nelchael has discovered a vulnerability in XnView / NView, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to an insecure RPATH being configured in the distributed "nview" and "xnview" binaries. This causes the affected binaries to look for shared libraries within the current working directory first. This can be exploited to execute arbitrary code with privileges of the user running the affected binaries by causing the binaries to load a malicious shared library (e.g. libXcursor.so) from the current directory.
Successful exploitation requires that the user runs the affected binaries from a directory that other users can write to.
The vulnerability has been confirmed in XnView version 1.70 and NView version 4.51. Other versions may also be affected.
