wu-ftpd 2.6.2 and earlier, with the restricted-gid option enabled, allows local users to bypass access restrictions by changing the permissions to prevent access to their home directory, which causes wu-ftpd to use the root directory instead.

ls in the fileutils or coreutils packages allows local users to consume a large amount of memory via a large -w value, which can be remotely exploited via applications that use ls, such as wu-ftpd.

An integer overflow in ls in the fileutils or coreutils packages may allow local users to cause a denial of service or execute arbitrary code via a large -w value, which could be remotely exploited via applications that use ls, such as wu-ftpd.
