"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2021:3015 advisory.

    Go Toolset provides the Go programming language tools and libraries. Go is alternatively known as golang.

    The go-toolset packages have been updated to version 1.15.14. (BZ#1982664)

    Security Fix(es):

    * golang: crypto/tls: certificate of wrong type is causing TLS client to panic (CVE-2021-34558)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * FIPS mode AES CBC CryptBlocks incorrectly re-initializes IV in file crypto/internal/boring/aes.go
    (BZ#1978557)

    For details, see Using Go Toolset linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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