Amazon Linux 2 : protobuf (ALAS-2023-1973)

high Nessus Plugin ID 172166

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of protobuf installed on the remote host is prior to 2.5.0-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-1973 advisory.

 A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including 3.16.1,3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures. A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a Denial of Service againstservices receiving unsanitized input. We recommend upgrading to versions 3.18.3, 3.19.5, 3.20.2, 3.21.6 for protobuf-cpp and 3.18.3, 3.19.5, 3.20.2, 4.21.6 for protobuf-python. Versions for 3.16 and 3.17 are no longer updated. (CVE-2022-1941)

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

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