Date: March 24, 2009
Bug(s): #216319, #257585
ID: 200903-38

Synopsis


Multiple vulnerabilities have been found in Squid which allow for remote
Denial of Service attacks.


Background


Squid is a full-featured web proxy cache.


Affected Packages

Package: net-proxy/squid

Architectures: All supported architectures


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-proxy/squid-2.7.6"
