GLSA-200512-18 : XnView: Privilege escalation

High Nessus Plugin ID 20371


The remote Gentoo host is missing one or more security-related patches.


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 allow a malicious user to effectively hijack XnView and execute arbitrary code with the privileges 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


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'
