I don't remember whether it added a group with gid 50 to /etc/group, but it makes the ftp area owned by group 50, and lists gid 50 as `ftp' in the anon-FTP /etc/group. However, on my ~~ 0.93R5 system /etc/group contains group 50 as `staff', and that group owns /usr/local. There doesn't appear to be a security problem, because the wu-ftpd doesn't ever seem (for example) to access files with gid 50, but this is anomalous and should be corrected.

Package: wu-ftpd Version: 2.4-13 The wu-ftpd package installs a minimal /etc/group file in the anonftp area. I don't remember whether it added a group with gid 50 to /etc/group, but it makes the ftp area owned by group 50, and lists gid 50 as `ftp' in the anon-FTP /etc/group. However, on my ~~ 0.93R5 system /etc/group contains group 50 as `staff', and that group owns /usr/local. There doesn't appear to be a security problem, because the wu-ftpd doesn't ever seem (for example) to access files with gid 50, but this is anomalous and should be corrected.
