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

1 net-proxy/squid < 2.7.6 > = 2.7.6
Description
===========
* The arrayShrink function in lib/Array.c can cause an array to
shrink to 0 entries, which triggers an assert error. NOTE: this issue
is due to an incorrect fix for CVE-2007-6239 (CVE-2008-1612).
* An invalid version number in a HTTP request may trigger an
assertion in HttpMsg.c and HttpStatusLine.c (CVE-2009-0478).
Impact
======
The issues allows for Denial of Service attacks against the service via
an HTTP request with an invalid version number and other specially
crafted requests.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Squid users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/squid-2.7.6"
