Debian Security Advisory DSA 076-1 security@debian.org

Package : most
Vulnerability : buffer overflow
Problem-Type : remote exploit
Debian-specific: no
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.
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.
We recommend that you upgrade your most package immediately.
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
