How to Fix CVE-2022-24988

To remediate this vulnerability, upgrade all affected Galois 2p8 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

galois_2p8 fixed: 0.1.2 
Upgrade galois_2p8 to 0.1.2
Verify Direct and Transitive Dependencies

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

inspect dependencies for galois_2p8

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-24988, inspect your project dependencies for Galois 2p8:

inspect dependencies for galois_2p8

Analyze the terminal output to locate any version of Galois 2p8 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow'), where the product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. In Galois 2p8, 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

In galois_2p8 before 0.1.2, PrimitivePolynomialField::new has an off-by-one buffer overflow for a vector.
