Amazon Linux 2023 : protobuf, protobuf-compiler, protobuf-devel (ALAS2023-2023-009)

medium Nessus Plugin ID 173092


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


It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-009 advisory.

- Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message.
Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater. (CVE-2021-22570)

Note that Nessus has not tested for this issue 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.
