DescriptionGitHub Advisory

The rsa crate is an RSA implementation written in rust. Prior to version 0.9.10, when creating a RSA private key from its components, the construction panics instead of returning an error when one of the primes is 1. Version 0.9.10 fixes the issue.

AnalysisAI

The RSA crate versions prior to 0.9.10 crash when constructing private keys with invalid prime components (such as 1), allowing an attacker to trigger a denial of service by providing malformed key material. This affects applications using the vulnerable RSA library for cryptographic operations. A patch is available in version 0.9.10 and later.

Technical ContextAI

Affects Rsa. The rsa crate is an RSA implementation written in rust. Prior to version 0.9.10, when creating a RSA private key from its components, the construction panics instead of returning an error when one of the primes is 1. Version 0.9.10 fixes the issue.

RemediationAI

A vendor patch is available — apply it immediately. Restrict network access to the affected service where possible.
