HylaFAX is a software package for sending and receiving facsimile messages.
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.
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.
As a workaround, administrators may consider adding passwords to all entries in the hosts.hfaxd file.
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.
