Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 096ab080-907c-11ec-bb14-002324b2fba8 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 this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
