Language:

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

The version of protobuf-c installed on the remote host is prior to 1.4.1-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-248 advisory.

 - Protobuf-c v1.4.0 was discovered to contain an invalid arithmetic shift via the function parse_tag_and_wiretype in protobuf-c/protobuf-c.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via unspecified vectors. (CVE-2022-33070)

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-c' to update your system.
