remove unwanted content.

|
James Ranson reported a vulnerability when JunkBuster is configured to
|
|
run in single-threaded mode, an attacker can modify the referrer
|
|
setting by getting a victim to request a specially crafted URL
|
|
(CAN-2005-1108). Tavis Ormandy of the Gentoo Linux Security Audit Team
|
|
identified a heap corruption issue in the filtering of URLs
|
|
(CAN-2005-1109).

|
<impact type="high">
|
|
<p>
|
|
If JunkBuster has been configured to run in single-threaded mode, an
|
|
attacker can disable or modify the filtering of Referrer: HTTP headers,
|
|
potentially compromising the privacy of users. The heap corruption
|
|
vulnerability could crash or disrupt the operation of the proxy,
|
|
potentially executing arbitrary code.
|

|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All JunkBuster users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-proxy/junkbuster-2.0.2-r3"</code>
|
