CBL Mariner 2.0 Security Update: expat (CVE-2024-8176)

high Nessus Plugin ID 233405

Synopsis

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

Description

The version of expat 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-2024-8176 advisory.

 - A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage. (CVE-2024-8176)

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.
