How to fix?

Upgrade electron to version 6.1.10, 7.2.2, 8.2.0 or higher.

Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Out-of-bounds Read. The input to sctp_load_addresses_from_init is verified by calling sctp_arethere_unrecognized_parameters, however there is a difference in how these functions handle parameter bounds. The function sctp_arethere_unrecognized_parameters does not process a parameter that is partially outside of the limit of the chunk, meanwhile, sctp_load_addresses_from_init will continue processing until a parameter that is entirely outside of the chunk occurs.

This means that the last parameter of a chunk is not always verified, which can lead to parameters with very short plen values being processed by sctp_load_addresses_from_init. This can lead to out-of-bounds reads whenever the plen is subtracted from the header len.
