Name of the Vulnerable Software and Affected Versions libpulse-binding versions prior to 1.2.1

Description The issue is related to a use-after-free problem in the libpulse-binding crate for Rust. Specifically, the get format info and get context methods of Stream objects can cause this issue due to the objects being constructed without setting an important flag to prevent destruction of the underlying C objects they reference upon their own destruction.

Recommendations For versions prior to 1.2.1, update to version 1.2.1 or newer to resolve the issue. As a temporary workaround, consider restricting the use of the get format info and get context methods of Stream objects until the update is applied.
