rPGP Panics on Malformed Untrusted Input

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

rPGP is a pure Rust implementation of OpenPGP. Prior to 0.14.1, rPGP allows an attacker to trigger rpgp crashes by providing crafted data. This vulnerability is fixed in 0.14.1.

During a security audit, [Radically Open Security](https://www.radicallyopensecurity.com/) 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. ### References The security audit was made possible by the [NLnet Foundation NGI Zero Core](https://nlnet.nl/core/) grant program [for rpgp](https://nlnet.nl/project/rPGP-cryptorefresh/).
