CVE-2020-16845: High severity IBM Security Guardium Insights vulnerability

Published Aug 6, 2020
·
Updated

A flaw was found in the Go encoding/binary package. Certain invalid inputs to the ReadUvarint or the ReadVarint causes those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This flaw possibly leads to processing more input than expected. The highest threat from this vulnerability is to system availability.

Other sources

Go before 1.13.15 and 14.x before 1.14.7 can have an infinite read loop in ReadUvarint and ReadVarint in encoding/binary via invalid inputs.

Go Language is vulnerable to a denial of service, caused by an infinite read loop in ReadUvarint and ReadVarint in encoding/binary. By sending a specially-crafted input, a remote attacker could exploit this vulnerability to cause a denial of service condition.
