+Subject: [PATCH 06/40] CVE-2014-0209: integer overflow of realloc() size in
+ lexAlias() from xorg/lib/libXfont commit
+ 05c8020a49416dd8b7510cbba45ce4f3fc81a7dc
+
+lexAlias() reads from a file in a loop. It does this by starting with a
+64 byte buffer.  If that size limit is hit, it does a realloc of the
+buffer size << 1, basically doubling the needed length every time the
+length limit is hit.
+
+Eventually, this will shift out to 0 (for a length of ~4gig), and that
+length will be passed on to realloc().  A length of 0 (with a valid
+pointer) causes realloc to free the buffer on most POSIX platforms,
+but the caller will still have a pointer to it, leading to use after
+free issues.
