+[CVE-2012-0804] Fix proxy response parser
+
+If proxy sends overlong HTTP vesion string, the string will be copied
+to unallocatd space (write_buf) causing heap overflow.
+
+This patch fixes it by ignoring the HTTP version string and checking
+the response line has been parsed correctly.
+
+See <https://bugzilla.redhat.com/show_bug.cgi?id=773699> for more
+details.
