Debian DSA-076-1 : most - buffer overflow

critical Nessus Plugin ID 14913

Synopsis

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

Description

Pavel Machek has found a buffer overflow in the `most' pager program.
 The problem is part of most's tab expansion where the program would write beyond the bounds two array variables when viewing a malicious file. This could lead into other data structures being overwritten which in turn could enable most to execute arbitrary code being able to compromise the users environment.

Solution

Upgrade the most package immediately.

This has been fixed in the upstream version 4.9.2 and an updated version of 4.9.0 for Debian GNU/Linux 2.2.
