An update of the go package has been released.
Go before 1.15.13 and 1.16.x before 1.16.5 has functions for DNS lookups that do not validate replies from DNS servers, and thus a return value may contain an unsafe injection (e.g., XSS) that does not conform to the RFC1035 format. (CVE-2021-33195)
In archive/zip in Go before 1.15.13 and 1.16.x before 1.16.5, a crafted file count (in an archive’s header) can cause a NewReader or OpenReader panic. (CVE-2021-33196)
In Go before 1.15.13 and 1.16.x before 1.16.5, some configurations of ReverseProxy (from net/http/httputil) result in a situation where an attacker is able to drop arbitrary headers.
(CVE-2021-33197)
In Go before 1.15.13 and 1.16.x before 1.16.5, there can be a panic for a large exponent to the math/big.Rat SetString or UnmarshalText method. (CVE-2021-33198)
The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic. (CVE-2021-34558)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
