Vulnerability CVE-2006-7094
Published: 2007-03-02   Modified: 2012-02-12

Description:
ftpd, as used by Gentoo and Debian Linux, sets the gid to the effective uid instead of the effective group id before executing /bin/ls, which allows remote authenticated users to list arbitrary directories with the privileges of gid 0 and possibly enable additional attack vectors.
