"The version of containerd installed on the remote host is prior to 1.7.20-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2DOCKER-2024-041 advisory.

    2024-08-27: CVE-2024-24790 was added to this advisory.

    2024-08-14: CVE-2023-47108 was removed from this advisory.

    2024-08-14: The severity of this advisory has been changed from Important to Medium.

    The protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid
    JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any
    value, or when the UnmarshalOptions.DiscardUnknown option is set. (CVE-2024-24786)

    The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected for IPv4-mapped IPv6
    addresses, returning false for addresses which would return true in their traditional IPv4 forms.
    (CVE-2024-24790)

    Package jose aims to provide an implementation of the Javascript Object Signing and Encryption set of
    standards. An attacker could send a JWE containing compressed data that used large amounts of memory and
    CPU when decompressed by Decrypt or DecryptMulti. Those functions now return an error if the decompressed
    data would exceed 250kB or 10x the compressed size (whichever is larger). This vulnerability has been
    patched in versions 4.0.1, 3.0.3 and 2.6.3. (CVE-2024-28180)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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