    untrusted input files.

    <p>
    Sarg (Squid Analysis Report Generator) is a tool that provides many
    informations about the Squid web proxy server users activities: time,
    sites, traffic, etc.
    </p>
  </background>
  <description>
    <p>
    Sarg doesn't properly check its input for abnormal content when
    processing Squid log files.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker using a vulnerable Squid as a proxy server or a
    reverse-proxy server can inject arbitrary content into the "User-Agent"
    HTTP client header, that will be processed by sarg, which will lead to
    the execution of arbitrary code, or JavaScript injection, allowing
    Cross-Site Scripting attacks and the theft of credentials.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All sarg users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/sarg-2.2.5&quot;</code>
  </resolution>
