Debian DSA-090-1 : xtel - symlink attack

low Nessus Plugin ID 14927

Synopsis

The remote Debian host is missing a security-related update.

Description

The xtel (an X emulator for minitel) package as distributed with Debian GNU/Linux 2.2 has two possible symlink attacks :

 - xteld creates a temporary file /tmp/.xtel-<user> without checking for symlinks.
 - when printing a hardcopy xtel would create a temporary file without protecting itself against symlink attacks.

Both problems have been fixed in version 3.2.1-4.potato.1 .

Solution

Upgrade the affected xtel package.
