+  <title>NASM: Buffer overflow vulnerability</title>
+  <synopsis>
+    NASM is vulnerable to a buffer overflow that allows an attacker to execute
+    arbitrary code through the use of a malicious object file.

+    <p>
+    NASM is a 80x86 assembler that has been created for portability
+    and modularity. NASM supports Pentium, P6, SSE MMX, and 3DNow
+    extensions. It also supports a wide range of objects formats (ELF,
+    a.out, COFF, ...), and has its own disassembler.
+    </p>
+  </background>
+  <description>
+    <p>
+    Jonathan Rockway discovered that NASM-0.98.38 has an unprotected
+    vsprintf() to an array in preproc.c. This code vulnerability may lead
+    to a buffer overflow and potential execution of arbitrary code.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could craft a malicious object file which, when
+    supplied in NASM, would result in the execution of arbitrary code with
+    the rights of the user running NASM.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All NASM users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=dev-lang/nasm-0.98.38-r1"</code>
