Hi

[I'm collecting the request in one mail, although maybe I should have
splitted up, apologies for that].

libgd fixed some issues in the git repositories, for which the
following three does not seem to have CVE ids:

1/ Fix potential unsigned underflow
Commit: https://github.com/libgd/libgd/commit/60bfb401ad5a4a8ae995dcd36372fe15c71e1a35

2/ Fix DOS vulnerability in gdImageCreateFromGd2Ctx()
Commit: https://github.com/libgd/libgd/commit/fe9ed49dafa993e3af96b6a5a589efeea9bfb36f

3/ Fix #354: Signed Integer Overflow gd_io.c
Commit: https://github.com/libgd/libgd/commit/69d2fd2c597ffc0c217de1238b9bf4d4bceba8e6
Issue: https://github.com/libgd/libgd/issues/354

Could you please assign CVE id's for those?

Regards,
Salvatore
