GHSA-9w97-2464-8783
No affected components available
Impact
Apps that allow downloads and programmatically destroy sessions may be vulnerable to a use-after-free. If a session is torn down while a native save-file dialog is open for a download, dismissing the dialog dereferences freed memory, which may lead to a crash or memory corruption.
Apps that do not destroy sessions at runtime, or that do not permit downloads, are not affected.
Workarounds
Avoid destroying sessions while a download save dialog may be open. Cancel pending downloads before session teardown.
Fixed Versions
41.0.0-beta.740.7.039.8.038.8.6
