Synopsis
=======
HylaFAX is subject to a vulnerability in its username matching code, potentially allowing remote users to bypass access control lists.
Background
=========
HylaFAX is a software package for sending and receiving facsimile messages.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/hylafax < 4.2.0-r2 >= 4.2.0-r2
Description
==========
The code used by hfaxd to match a given username and hostname with an entry in the hosts.hfaxd file is insufficiently protected against malicious entries.
Impact
=====
If the HylaFAX installation uses a weak hosts.hfaxd file, a remote attacker could authenticate using a malicious username or hostname and bypass the intended access restrictions.
Workaround
=========
As a workaround, administrators may consider adding passwords to all entries in the hosts.hfaxd file.
Resolution
=========
All HylaFAX users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/hylafax-4.2.0-r2"
Note: Due to heightened security, weak entries in the hosts.hfaxd file may no longer work. Please see the HylaFAX documentation for details of accepted syntax in the hosts.hfaxd file.
