Amazon Linux 2 : protobuf (ALAS-2023-1948)

medium Nessus Plugin ID 171821

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 ALAS2-2023-1948 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.

Solution

Run 'yum update protobuf' to update your system.
