Description Ratul Gupta 2013-09-16 06:54:18 UTC
It is found that davfs2, a tool for connecting to WebDAV, might be using the system() insecurely. The issue is since mount_davfs2 is setuid, using the system() call could result in privilege escalation.

I'm building davfs-1.4.7-3.fc{18,19,20}, which includes the patch from upstream for this. Let me know if there's anything special I need to do here.
