"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by
multiple vulnerabilities as referenced in the SUSE-SU-2022:0724-1 advisory.

  - 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.");
