+  <title>gzip: Multiple vulnerabilities</title>
+  <synopsis>
+    gzip contains multiple vulnerabilities potentially allowing an attacker to
+    execute arbitrary commands.

+    <package name="app-arch/gzip" auto="yes" arch="*">

+  <background>
+    <p>
+    gzip (GNU zip) is a popular compression program. The included
+    zgrep utility allows you to grep gzipped files in place.
+    </p>
+  </background>
+  <description>
+    <p>
+    The gzip and gunzip programs are vulnerable to a race condition
+    when setting file permissions (CAN-2005-0988), as well as improper
+    handling of filename restoration (CAN-2005-1228). The zgrep utility
+    improperly sanitizes arguments, which may come from an untrusted source
+    (CAN-2005-0758).
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    These vulnerabilities could allow arbitrary command execution,
+    changing the permissions of arbitrary files, and installation of files
+    to an aribitrary location in the filesystem.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All gzip users should upgrade to the latest stable version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/gzip-1.3.5-r6&quot;</code>
