-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : htdig SUMMARY : ht://Dig DoS and remote exposure DATE : 2001-10-10 19:17:00 ID : CLA-2001:429 RELEVANT RELEASES : 5.0, 5.1, 6.0, 7.0 - ------------------------------------------------------------------------- DESCRIPTION The ht://Dig system is a complete world wide web indexing and searching system for a small domain or intranet. The htsearch program is the component used for queries and can be used with a web server using a cgi interface. Nergal <nergal at 7bulls.com> reported[1] a vulnerability in htsearch wich allows a remote user to pass the -c parameter (use specific config file) to the program even when it's running as a cgi. A malicious user could point to a file like /dev/zero and let the server run in an endless loop, trying to read config parameters from there. Also, if the user has write permission on the server and can create a file with specific entries, he/she can point the server to it and retrive any file readable by the webserver UID. SOLUTION All htdig users should upgrade.
