Created an attachment (id=4838)

Crash(es) in SigComp UDVM

The attached file was created by fuzzing 4723-gm-keep-test1.snoop. According
Valgrind there are at least two problems:

1. sigcomp_state_hdlr.c:787 is reading an uninitialized value. This appears to
be from sigcomp_init_udvm not setting the first 8 bytes of its buffers.

2. sigcomp-udvm.c:929 is writing one byte past the end of the buffer.

I probably won't have time to look at this further until tomorrow.
