DescriptionNVD

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.7
40.7.0
39.8.0
38.8.6

Use-after-free in Electron framework allows memory corruption when native save-file dialogs remain open during session teardown. Affected Electron versions prior to 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.7 enable local attackers with UI interaction to trigger freed memory dereference via downloaded files, potentially causing application crashes or memory corruption. …
