+  <title>Squid: Denial of service when using NTLM authentication</title>
+  <synopsis>
+    Squid is vulnerable to a denial of service attack which could crash its
+    NTLM helpers.

+    <p>
+    Squid is a full-featured Web Proxy Cache designed to run on Unix
+    systems. It supports proxying and caching of HTTP, FTP, and other URLs,
+    as well as SSL support, cache hierarchies, transparent caching, access
+    control lists and many other features.
+    </p>

+  <description>
+    <p>
+    Squid 2.5.x versions contain a bug in the functions ntlm_fetch_string()
+    and ntlm_get_string() which lack checking the int32_t offset "o" for
+    negative values.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could cause a denial of service situation by sending
+    certain malformed NTLMSSP packets if NTLM authentication is enabled.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    Disable NTLM authentication by removing any "auth_param ntlm program
+    ..." directives from squid.conf or use ntlm_auth from Samba-3.x.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Squid users should upgrade to the latest stable version:
+    </p>
+    <code>
+    # emerge sync
+    
+    # emerge -pv &quot;&gt;=net-www/squid-2.5.6-r2&quot;
+    # emerge &quot;&gt;=net-www/squid-2.5.6-r2&quot;</code>
