The remote host is affected by the vulnerability described in GLSA-200512-18
(XnView: Privilege escalation)
Krzysiek Pawlik of Gentoo Linux discovered that the XnView package

This would allow a malicious user to effectively hijack XnView and
execute arbitrary code with the rights 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
All XnView users on the x86 platform should upgrade to the latest
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-misc/xnview-1.70-r1"
