CVE-2019-20503

Public on 2020-03-06
Modified on 2020-04-23
Description

The Mozilla Foundation Security Advisory describes this flaw as:

The inputs to `sctp_load_addresses_from_init` are verified by `sctp_arethere_unrecognized_parameters`; however, the two functions handled parameter bounds differently, resulting in out of bounds reads when parameters are partially outside a chunk.
