Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
HylaFAX is vulnerable to arbitrary code execution and unauthorized |
| 19 |
access vulnerabilities. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
HylaFAX is an enterprise-class system for sending and receiving |
| 25 |
facsimile messages and for sending alpha-numeric pages. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 net-misc/hylafax < 4.2.3-r1 >= 4.2.3-r1 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Patrice Fournier discovered that HylaFAX runs the notify script on |
| 39 |
untrusted user input. Furthermore, users can log in without a password |
| 40 |
when HylaFAX is installed with the pam USE-flag disabled. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
An attacker could exploit the input validation vulnerability to run |
| 46 |
arbitrary code as the user running HylaFAX, which is usually uucp. The |
| 47 |
password vulnerability could be exploited to log in without proper user |
| 48 |
credentials. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All HylaFAX users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=net-misc/hylafax-4.2.3-r1" |
| 62 |
