Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two vulnerabilities have been found in Squid which make it susceptible |
| 19 |
to Denial of Service attacks. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Squid is a multi-protocol proxy server. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 net-proxy/squid < 2.6.7 >= 2.6.7 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Squid fails to correctly handle ftp:// URI's. There is also an error in |
| 38 |
the external_acl queue which can cause an infinite looping condition. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
An attacker could attempt to retrieve a specially crafted URI via a |
| 44 |
Squid server causing the service to crash. If an attacker could |
| 45 |
generate a sufficiently high load on the Squid services, they could |
| 46 |
cause a Denial of Service by forcing Squid into an infinite loop. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Squid users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.7" |
| 60 |
|
| 61 |
