How to Fix GHSA-c7ph-f7jm-xv4w

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

pgp fixed: 0.19.0 
Upgrade pgp to 0.19.0
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 pgp

How to Check if You Are Affected

To determine whether your application is affected by GHSA-c7ph-f7jm-xv4w, inspect your project dependencies for Pgp:

inspect dependencies for pgp

Analyze the terminal output to locate any version of Pgp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.19.0), 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-354: Improper Validation of Integrity Check Value, where the product does not validate or incorrectly validates the integrity check values or "checksums" of a message. this may prevent it from detecting if the data has been modified or corrupted in transmission. In Pgp, 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

### Summary For some messages, rPGP returned incorrectly decrypted data without signaling that integrity protection was invalid. ### Details When decrypting SEIPD (Symmetrically Encrypted and Integrity Protected Data Packet), rPGP previously did not under all circumstances report the absence of valid integrity protection to callers of the library. ### Impact While the resulting invalid decryption output is not attacker controlled, its contents may be a security concern if an attacker can gain access to it. ### Attribution Discovered internally in the course of rPGP development work.
