How to Fix CVE-2023-53160

To remediate this vulnerability, upgrade all affected Sequoia openpgp dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

sequoia-openpgp fixed: 1.1.1 
Upgrade sequoia-openpgp to 1.1.1
sequoia-openpgp fixed: 1.8.1 
Upgrade sequoia-openpgp to 1.8.1
sequoia-openpgp fixed: 1.16.0 
Upgrade sequoia-openpgp to 1.16.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for sequoia-openpgp

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-53160, inspect your project dependencies for Sequoia openpgp:

inspect dependencies for sequoia-openpgp

Analyze the terminal output to locate any version of Sequoia openpgp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In Sequoia openpgp, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Affected versions of the crate have several bugs where attacker-controlled input can result in the use of an out-of-bound array index. Rust detects the use of the out-of-bound index and causes the application to panic. An attacker may be able to use this to cause a denial-of-service. However, it is not possible for an attacker to read from or write to the application's address space.
