How to Fix CVE-2018-25028

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

libpulse-binding fixed: 1.2.1 
Upgrade libpulse-binding to 1.2.1
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 libpulse-binding

How to Check if You Are Affected

To determine whether your application is affected by CVE-2018-25028, inspect your project dependencies for Libpulse binding:

inspect dependencies for libpulse-binding

Analyze the terminal output to locate any version of Libpulse binding in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.1), 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-416: Use After Free, where the product reuses or references memory after it has been freed. at some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. In Libpulse binding, 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 contained 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.
