[rt-users] [rt-announce] RT 2.0.8_01 - CRITICAL SECURITY FIX

[Jesse Vincent]

Earlier today, I was alerted to a security vulnerability in RT's command
line administration tool, rtadmin by Jay Kramer at Mojomole.com.

The vulnerability, as Jay discovered, allows _local_ shell users to access
RT's commandline administrative tool with RT superuser permissions. If you
have local shell users who have access to execute the RT binaries but who are 
not trusted administrators, you MUST upgrade to RT 2.0.8_01 as soon as humanly
possible.

Until you upgrade, we recommend that you disable the rtadmin program by
executing the following command:

	chmod 000 /path/to/rt/bin/rtadmin

RT 2.0.8_01 is immediately available from:

	ftp://ftp.fsck.com/pub/rt/release/rt-2-0-8_01.tar.gz

A diff between RT 2.0.8 and RT 2.0.8_01 is attached to this message.

Thanks very much to Jay Kramer for his quick and professional handling of 
this vulnerability report.
