+Subject: [PATCH] fserve: bounds-check cumulative glyph data writes in
+ fs_read_glyphs
+
+fs_read_glyphs() copies each glyph's bitmap into a single allbits
+buffer allocated to rep->nbytes bytes. The per-glyph guard validates
+only that the source slice (position, length) lies within the pbitmaps
+source buffer. It does not check whether the running destination cursor
+has exceeded the allocation.
+
+A malicious font server can send overlapping source offsets (e.g. 1000
+glyphs each referencing {position:0, length:64} with nbytes=64). Each
+individual source range passes validation, but the cumulative writes
+total 64000 bytes into a 64-byte destination buffer.
+
+Interestingly there was an unconditional debug printf in place that
+sort-of warned about this but didn't prevent this. Let's remove that and
+instead use the actual check to bail out before we run OOB.
+
+A regression test is included that sends 100 glyphs each referencing
+the same 64-byte source slice into a 64-byte destination buffer, and
+verifies the library rejects the overflow.
