[GLSA-200512-18] XnView: Privilege escalation

Vulnerability Assessment Summary
XnView: Privilege escalation

Detailed Explanation for this Vulnerability Assessment
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
for IA32 used the DT_RPATH field insecurely, causing the dynamic loader
to search for shared libraries in potentially untrusted directories.

Impact

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 permit a malicious user to effectively hijack XnView and
execute arbitrary code with the rights of the user running the
program.

Workaround

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


Solution:
All XnView users on the x86 platform should upgrade to the latest
version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-misc/xnview-1.70-r1"


Network Security Threat Level: Medium
