"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:1819 advisory.

  - Go before 1.16.9 and 1.17.x before 1.17.2 has a Buffer Overflow via large arguments in a function
    invocation from a WASM module, when GOARCH=wasm GOOS=js is used. (CVE-2021-38297)

  - In archive/zip in Go before 1.16.8 and 1.17.x before 1.17.1, a crafted archive header (falsely designating
    that many files are present) can cause a NewReader or OpenReader panic. NOTE: this issue exists because of
    an incomplete fix for CVE-2021-33196. (CVE-2021-39293)

  - ImportedSymbols in debug/macho (for Open or OpenFat) in Go before 1.16.10 and 1.17.x before 1.17.3
    Accesses a Memory Location After the End of a Buffer, aka an out-of-bounds slice situation.
    (CVE-2021-41771)

  - Go before 1.16.10 and 1.17.x before 1.17.3 allows an archive/zip Reader.Open panic via a crafted ZIP
    archive containing an invalid name or an empty filename field. (CVE-2021-41772)

  - Rat.SetString in math/big in Go before 1.16.14 and 1.17.x before 1.17.7 has an overflow that can lead to
    Uncontrolled Memory Consumption. (CVE-2022-23772)

  - cmd/go in Go before 1.16.14 and 1.17.x before 1.17.7 can misinterpret branch names that falsely appear to
    be version tags. This can lead to incorrect access control if an actor is supposed to be able to create
    branches but not tags. (CVE-2022-23773)

  - Curve.IsOnCurve in crypto/elliptic in Go before 1.16.14 and 1.17.x before 1.17.7 can incorrectly return
    true in situations with a big.Int value that is not a valid field element. (CVE-2022-23806)

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