Severity: High Title: HylaFAX: Multiple vulnerabilities Date: January 06, 2006 Bugs: #116389 ID: 200601-03


Synopsis

HylaFAX is vulnerable to arbitrary code execution and unauthorized access vulnerabilities.

Background

HylaFAX is an enterprise-class system for sending and receiving facsimile messages and for sending alpha-numeric pages.

Affected packages

-------------------------------------------------------------------
 Package           /  Vulnerable  /                     Unaffected
-------------------------------------------------------------------

1 net-misc/hylafax < 4.2.3-r1 >= 4.2.3-r1

Description

Patrice Fournier discovered that HylaFAX runs the notify script on untrusted user input. Furthermore, users can log in without a password when HylaFAX is installed with the pam USE-flag disabled.

Impact

An attacker could exploit the input validation vulnerability to run arbitrary code as the user running HylaFAX, which is usually uucp. The password vulnerability could be exploited to log in without proper user credentials.

Workaround

There is no known workaround at this time.

Resolution

All HylaFAX users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/hylafax-4.2.3-r1&quot;
