GHSA-9RMP-2568-59RV

Vulnerability from github – Published: 2024-12-05 17:30 – Updated: 2025-12-26 16:30

Summary

rPGP Panics on Malformed Untrusted Input

Details

During a security audit, Radically Open Security discovered several reachable edge cases which allow an attacker to trigger rpgp crashes by providing crafted data.

Impact

When processing malformed input, rpgp can run into Rust panics which halt the program.

This can happen in the following scenarios: * Parsing OpenPGP messages from binary or armor format * Decrypting OpenPGP messages via decrypt_with_password() * Parsing or converting public keys * Parsing signed cleartext messages from armor format * Using malformed private keys to sign or encrypt

Given the affected components, we consider most attack vectors to be reachable by remote attackers during typical use cases of the rpgp library. The attack complexity is low since the malformed messages are generic, short, and require no victim-specific knowledge.

The result is a denial-of-service impact via program termination. There is no impact to confidentiality or integrity security properties.

Versions and Patches

All recent versions are affected by at least some of the above mentioned issues.

The vulnerabilities have been fixed with version 0.14.1. We recommend all users to upgrade to this version.

Summary

Panics on Malformed Untrusted Input

Details

During a security audit, Radically Open Security discovered several reachable edge cases which allow an attacker to trigger rpgp crashes by providing crafted data.

Impact

When processing malformed input, rpgp can run into Rust panics which halt the program.

This can happen in the following scenarios:

Parsing OpenPGP messages from binary or armor format
Decrypting OpenPGP messages via decrypt_with_password()
Parsing or converting public keys
Parsing signed cleartext messages from armor format
Using malformed private keys to sign or encrypt

Given the affected components, we consider most attack vectors to be reachable by remote attackers during typical use cases of the rpgp library. The attack complexity is low since the malformed messages are generic, short, and require no victim-specific knowledge.

The result is a denial-of-service impact via program termination. There is no impact to confidentiality or integrity security properties.

Versions and Patches

All recent versions are affected by at least some of the above mentioned issues.

The vulnerabilities have been fixed with version 0.14.1. We recommend all users to upgrade to this version.
