What is CVE-2024-58261?

CVE-2024-58261 is a low-severity security vulnerability in sequoia-openpgp (rust), affecting versions >= 1.13.0, < 1.21.0. It is fixed in 1.21.0.

How severe is CVE-2024-58261?

CVE-2024-58261 has a CVSS score of 2.9 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of sequoia-openpgp are affected by CVE-2024-58261?

sequoia-openpgp (rust) versions >= 1.13.0, < 1.21.0 is affected.

Is there a fix for CVE-2024-58261?

Yes. CVE-2024-58261 is fixed in 1.21.0. Upgrade to this version or later.

Is CVE-2024-58261 exploitable, and should I be worried?

Whether CVE-2024-58261 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2024-58261 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

There is a denial-of-service vulnerability in sequoia-openpgp, our crate providing a low-level interface to our OpenPGP implementation. When triggered, the process will enter an infinite loop.

Many thanks to Andrew Gallagher for disclosing the issue to us.

Details

The RawCertParser does not advance the input stream when encountering unsupported cert (primary key) versions, resulting in an infinite loop.

The fix introduces a new raw-cert-specific cert::raw::Error::UnuspportedCert.

Affected software

sequoia-openpgp 1.13.0
sequoia-openpgp 1.14.0
sequoia-openpgp 1.15.0
sequoia-openpgp 1.16.0
sequoia-openpgp 1.17.0
sequoia-openpgp 1.18.0
sequoia-openpgp 1.19.0
sequoia-openpgp 1.20.0
Any software built against a vulnerable version of sequoia-openpgp which is directly or indirectly using the interface sequoia_openpgp::cert::raw::RawCertParser. Notably, this includes all software using the sequoia_cert_store crate.

Impact

Any software directly or indirectly using the interface sequoia_openpgp::cert::raw::RawCertParser. Notably, this includes all
software using the sequoia_cert_store crate.

CVE-2024-58261 has a CVSS score of 2.9 (Low). The vector is requires local access, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.21.0); upgrading removes the vulnerable code path.

Affected versions

sequoia-openpgp (>= 1.13.0, < 1.21.0)

Security releases

sequoia-openpgp → 1.21.0 (rust)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
