+  <title>Linux-PAM: Privilege escalation</title>
+  <synopsis>
+    An error in the handling of user names of Linux-PAM might allow remote
+    attackers to cause a Denial of Service or escalate privileges.

+    <p>
+    Linux-PAM (Pluggable Authentication Modules) is an architecture
+    allowing the separation of the development of privilege granting
+    software from the development of secure and appropriate authentication
+    schemes.
+    </p>
+  </background>
+  <description>
+    <p>
+    Marcus Granado repoted that Linux-PAM does not properly handle user
+    names that contain Unicode characters. This is related to integer
+    signedness errors in the pam_StrTok() function in libpam/pam_misc.c.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could exploit this vulnerability to cause a Denial of
+    Service. A remote authenticated attacker could exploit this
+    vulnerability to log in to a system with the account of a user that has
+    a similar user name, but with non-ASCII characters.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Linux-PAM users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=sys-libs/pam-1.0.4"</code>
