Description

Low severity (DoS) vulnerability in sequoia-openpgp

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.

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.

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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is high, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability low.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: None.
  • Integrity impact: None.
  • Availability impact: Low — limited, and the attacker does not choose what is affected.

Weakness class

CVE-2024-58261 is classified as CWE-835: Infinite Loop. A loop condition can never become false for some inputs, hanging the process.
