How to Fix CVE-2022-41957

To remediate this vulnerability, upgrade all affected Hummus dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

hummus fixed: Latest secure release 
npm install hummus@Latest secure release
muhammara fixed: 3.4.0 
npm install muhammara@3.4.0
muhammara fixed: 2.6.2 
npm install muhammara@2.6.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls hummus

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-41957, inspect your project dependencies using npm:

npm ls hummus

Analyze the terminal output to locate any version of Hummus in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.4.0), your application is affected.

Note: The npm ls hummus command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-690: Unchecked Return Value to NULL Pointer Dereference, where the product does not check for an error after calling a function that can return with a null pointer if the function fails, which leads to a resultant null pointer dereference. In Hummus, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The package muhammara before 2.6.2, from 3.0.0 and before 3.3.0; all versions of package hummus are vulnerable to Denial of Service (DoS) when supplied with a maliciously crafted PDF file to be parsed. ### Patches It has been patched in 3.4.0 and has been backported to 2.6.2 There is no patch for hummus, currently ### Workarounds Do not process files from untrusted sources or update. Replace hummus with muhammara ### References https://github.com/julianhille/MuhammaraJS/pull/235 https://github.com/julianhille/MuhammaraJS/pull/238
