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 against services 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 Versions for 3.16 and 3.17 are no longer updated.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)

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

Solution

Run 'yum update protobuf' to update your system.
