high Nessus Plugin ID 147697

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The Go project reports :

The Decode, DecodeElement, and Skip methods of an xml.Decoder provided by xml.NewTokenDecoder may enter an infinite loop when operating on a custom xml.TokenReader which returns an EOF in the middle of an open XML element.

The Reader.Open API, new in Go 1.16, will panic when used on a ZIP archive containing files that start with '../'.

Solution

Update the affected package.
