Which packages are affected by GHSA-ghpq-vjxw-ch5w?

GHSA-ghpq-vjxw-ch5w affects the following packages: libpulse-binding (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-ghpq-vjxw-ch5w?

Update libpulse-binding to 1.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-ghpq-vjxw-ch5w is resolved across your whole dependency graph.

How do I detect GHSA-ghpq-vjxw-ch5w in my crates.io dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for libpulse-binding, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-ghpq-vjxw-ch5w if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-ghpq-vjxw-ch5w?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-ghpq-vjxw-ch5w can be triaged on real exposure rather than presence alone.

Is GHSA-ghpq-vjxw-ch5w actively exploited in the wild?

No public exploit code has been indexed for GHSA-ghpq-vjxw-ch5w yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-ghpq-vjxw-ch5w?

GHSA-ghpq-vjxw-ch5w has an EPSS (Exploit Prediction Scoring System) score of 1.3%, placing it in the 70th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-ghpq-vjxw-ch5w?

GHSA-ghpq-vjxw-ch5w is classified as Use After Free (CWE-416). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-ghpq-vjxw-ch5w published, and has it been updated?

GHSA-ghpq-vjxw-ch5w was published on August 25, 2021 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.

Description

Overview

Version 1.2.1 of the libpulse-binding Rust crate, released on the 15th of June 2018, fixed a pair of use-after-free issues with the objects returned by the get_format_info and get_context methods of Stream objects. These objects were mistakenly being constructed without setting an important flag to prevent destruction of the underlying C objects they reference upon their own destruction.

This advisory is being written retrospectively, having previously only been noted in the changelog. No CVE assignment was sought.

Patches

Users are required to update to version 1.2.1 or newer.

Versions older than 1.2.1 have been yanked from crates.io. This was believed to have already been done at the time of the 1.2.1 release, but upon double checking now they were found to still be available, so has been done now (22nd October 2020).
