Rocky Linux 8 : go-toolset:rhel8 (RLSA-2021:3076)

high Nessus Plugin ID 184704


The remote Rocky Linux host is missing one or more security updates.


The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:3076 advisory.

- encoding/xml in Go before 1.15.9 and 1.16.x before 1.16.1 has an infinite loop if a custom TokenReader (for xml.NewTokenDecoder) returns EOF in the middle of an element. This can occur in the Decode, DecodeElement, or Skip method. (CVE-2021-27918)

- net/http in Go before 1.15.12 and 1.16.x before 1.16.4 allows remote attackers to cause a denial of service (panic) via a large header to ReadRequest or ReadResponse. Server, Transport, and Client can each be affected in some configurations. (CVE-2021-31525)

- 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)

- 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 these issues but has instead relied only on the application's self-reported version number.
