[Shorewall-announce] URGENT: Shorewall Security Vulnerability ------------------------------------------------------------------------ Javier Fernández-Sanguino Peña has discovered an exploitable vulnerability in the way that Shorewall handles temporary files and directories. The vulnerability can allow a non-root user to cause arbitrary files on the system to be overwritten. LEAF Bering and Bering uClibc users are generally not at risk due to the fact that LEAF boxes do not typically allow logins by non-root users. For 2.0 users, the problem is corrected in version 2.0.3a: http://shorewall.net/pub/shorewall/shorewall-2.0.3a ftp://shorewall.net/pub/shorewall/shorewall-2.0.3a For 1.4 users, the correct version is: http://shorewall.net/pub/shorewall/shorewall-1.4.10f ftp://shorewall.net/pub/shorewall/shorewall-1.4.10f I would appreciate immediate feedback on the 1.4.10f version; given that I don't have any 1.4 systems remaining, I couldn't fully test that code. -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep at shorewall.net
