Title: FTPFS mount Buffer Overflow Vulnerability
Severity: MODERATE
Description:
FTPFS is a Linux kernel module allowing users to mount remote files from any standard FTP server as a local filesystem.
A version of FTPFS is vulnerable to a buffer overflow leading to a denial of service, and potentially execution of arbitrary code.
By supplying excess input to the 'user' argument of a 'mount' command with type set to ftpfs, it is possible for user-supplied data to be executed at the kernel level.
