Amazon Linux 2023 : protobuf, protobuf-compiler, protobuf-devel (ALAS2023-2023-049)

high Nessus Plugin ID 173134


The remote Amazon Linux 2023 host is missing a security update.


It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-049 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 Versions for 3.16 and 3.17 are no longer updated.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)

- A parsing issue with binary data in protobuf-java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6 and 3.16.3 can lead to a denial of service attack. Inputs containing multiple instances of non-repeated embedded messages with repeated or unknown fields causes objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses. We recommend updating to the versions mentioned above. (CVE-2022-3171)

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


Run 'dnf update protobuf --releasever=2023.0.20230222 ' to update your system.
