XnView is an efficient multimedia viewer, browser and converter,
distributed free for non-commercial use.
Krzysiek Pawlik of Gentoo Linux discovered that the XnView package for
IA32 used the DT_RPATH field insecurely, causing the dynamic loader to
search for shared libraries in potentially untrusted directories.
<impact type="normal">
A local attacker could create a malicious shared object that would be
loaded and executed when a user attempted to use an XnView utility.
This would allow a malicious user to effectively hijack XnView and
execute arbitrary code with the privileges of the user running the
The system administrator may use the chrpath utility to remove the
DT_RPATH field from the XnView utilities:
# emerge app-admin/chrpath
# chrpath --delete /opt/bin/nconvert /opt/bin/nview /opt/bin/xnview</code>
All XnView users on the x86 platform should upgrade to the latest
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=x11-misc/xnview-1.70-r1&quot;</code>
