+Subject: [PATCH 01/33] unchecked malloc may allow unauthed client to crash
+ Xserver [CVE-2014-8091]
+
+authdes_ezdecode() calls malloc() using a length provided by the
+connection handshake sent by a newly connected client in order
+to authenticate to the server, so should be treated as untrusted.
+
+It didn't check if malloc() failed before writing to the newly
+allocated buffer, so could lead to a server crash if the server
+fails to allocate memory (up to UINT16_MAX bytes, since the len
+field is a CARD16 in the X protocol).
