From: secure@conectiva.com.br To: conectiva-updates@papaleguas.conectiva.com.br, linuxlist@securityportal.com, lwn@lwn.net, bugtraq@securityfocus.com, security-alerts@linuxsecurity.com Subject: [CLA-2001:410] Conectiva Linux Security Announcement - imp Date: Wed, 25 Jul 2001 18:25:55 -0300 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : imp SUMMARY : Remote vulnerability affects the IMP webmail system DATE : 2001-07-25 18:21:00 ID : CLA-2001:410 RELEVANT RELEASES : 4.1, 4.2, 5.0, 5.1, 6.0, 7.0 - ------------------------------------------------------------------------- DESCRIPTION "imp" is a webmail system that uses the "horde" framework. The authors have released new versions of IMP and HORDE that address security vulnerabilities disclosed by giancarlo pinerolo (giancarlo@navigare.net) and Nick Cleaton (nick@cleaton.net), as well as one problem found during an internal audit. 1. A remote attacker could trick the server into fetching scripts from another host and then execute them. This could be used to get access to the server running this webmail system. 2. An attacker might also execute malicious javascript code in the browser of an user who is reading an email sent by the attacker with special "javascript:" encodings. 3. An attacker could make the server read a file called "prefs.lang" and execute it as PHP code. The attacker would have to be able to create that file first, which implies at least some sort of write access, such as one provided by a shell account, or ftp upload. SOLUTION It is recommended that all users of the IMP webmail system (and HORDE) upgrade their systems.
