Golang 1.26.x < 1.26.6 DoS

high Nessus Plugin ID 338315

Language:

Synopsis

An application installed on the remote host is affected by a denial of service vulnerability.

Description

The version of Golang running on the remote host is 1.26.x prior to 1.26.6. It is, therefore, affected by a denial of service vulnerability in the bundled golang.org/x/net/dns/dnsmessage package. Parsing an invalid SVCB or HTTPS RR can panic when the size of a parameter value overflows the message buffer.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Golang Go version 1.26.6 or later.
