Unspecified vulnerability in glFTPd before 2.01 RC5 allows remote attackers to bypass IP checks via a crafted DNS hostname, possibly a hostname that appears to be an IP address.

Multiple directory traversal vulnerabilities in sitenfo.sh, sitezipchk.sh, and siteziplist.sh in Glftpd 1.26 to 2.00 allow remote authenticated users to (1) determine the existence of arbitrary files, (2) list files in restricted directories, or (3) read arbitrary files from within ZIP or gzip files, via .. (dot dot) sequences and globbing ("*") characters in a SITE NFO command.
