DESCRIPTION:
Two vulnerabilities have been reported in Erlang/OTP, which can be
exploited by malicious people to cause a crash and potentially
compromise a vulnerable system.

1) An error within the handling of 64-bit integers can be exploited
to e.g. crash the emulator.

Note: This only affects drivers using the "ERL_DRV_INT64" or
"ERL_DRV_UINT64" functions.

This vulnerability is reported in version R13B03 and later but prior
to R14B.

2) An error within the "erl_term_len()" function can cause too large
or too small values to be returned.

This vulnerability is reported in version R9B and later but prior to
R14B01.

SOLUTION:
Update to version R14B02.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
