How to Fix CVE-2022-31264

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

solana_rbpf fixed: 0.2.29 
Upgrade solana_rbpf to 0.2.29
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 solana_rbpf

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-31264, inspect your project dependencies for Solana rbpf:

inspect dependencies for solana_rbpf

Analyze the terminal output to locate any version of Solana rbpf in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.29), 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-190: Integer Overflow or Wraparound, where the product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. this occurs when an integer value is incremented to a value that is too large to store in the associated representation. when this occurs, the value may become a very small or negative number. In Solana rbpf, 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

Solana solana_rbpf before 0.2.29 has an addition integer overflow via invalid ELF program headers. elf.rs has a panic via a malformed eBPF program.
