Name of the Vulnerable Software and Affected Versions glib versions 0.15.0 and later

Description The VariantStrIter::impl get function was unsound, resulting in undefined behavior due to an immutable reference being passed to a C function that mutates the pointer in-place. This caused crashes due to NULL pointer dereferences when calling std::ffi::CStr::from ptr. The issue was present since glib v0.15.0 and was fixed by passing the out-argument pointer explicitly as &mut p instead of &p.

Recommendations For glib versions 0.15.0 and later, update the VariantStrIter::impl get function to pass the out-argument pointer explicitly as &mut p instead of &p to fix the issue.
