CBL Mariner 2.0 Security Update: curl (CVE-2023-38039)

high Nessus Plugin ID 183439

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of curl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-38039 advisory.

 - When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory. (CVE-2023-38039)

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

Solution

Update the affected packages.
