Description:
Xavier de Leon has reported two vulnerabilities in Rocks, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerabilities are caused due to improper filtering of arguments passed to the mount-loop and umount-loop setuid applications before using them as parameter in a "system()" call.
Successful exploitation allows execution of arbitrary code with root privileges.
The vulnerabilities have been reported in version 4.1. Other versions may also be affected.
Solution:
The vulnerabilities have been fixed in version 4.2 beta.
Provided and/or discovered by:
Xavier de Leon
