RHSA-2003:038 - Security Advisory

Topic

Updated Internet Message packages are available that fix the insecure
handling of temporary files.

[Updated 9 April 2003]
Added packages for Red Hat Linux Advanced Workstation, Red Hat Enterprise
Linux ES, and Red Hat Enterprise Linux WS.

Description

Internet Message (IM) consists of a set of user interface commands and
backend Perl5 libraries to integrate email and the NetNews user interface.
These commands are designed to be used from both the Mew mail reader for
Emacs and the command line.

A vulnerability has been discovered by Tatsuya Kinoshita in the way two IM
utilities create temporary files. By anticipating the names used to
create files and directories stored in the /tmp directory, it may be
possible for a local attacker to corrupt or modify data as another user.

Users of IM are advised to install these packages which contain a
backported patch to correct these issues.
