-Subject: [PATCH] bdfReadCharacters: bailout if a char's bitmap cannot be read
- [CVE-2015-1803]
-
-Previously would charge on ahead with a NULL pointer in ci->bits, and
-then crash later in FontCharInkMetrics() trying to access the bits.
-
-Found with afl-1.23b.

-Subject: [PATCH] bdfReadCharacters: ensure metrics fit into xCharInfo struct
- [CVE-2015-1804]
-
-We use 32-bit ints to read from the bdf file, but then try to stick
-into a 16-bit int in the xCharInfo struct, so make sure they won't
-overflow that range.
-
-Found by afl-1.24b.
-
-v2: Verify that additions won't overflow 32-bit int range either.
-v3: As Julien correctly observes, the previous check for bh & bw not
- being < 0 reduces the number of cases we need to check for overflow.
