Severity: Normal Title: HylaFAX: hfaxd unauthorized login vulnerability Date: January 11, 2005 Bugs: #75941 ID: 200501-21

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.
