Issue 444957: Heap-use-after-free in OpenPDFInReaderBubbleView::ButtonPressed

Reported by, Dec 24 2014

Issue description

Chrome Version: 41.0.2257.0 canary / 39.0.2171.95 dev-m
Operating System: Win7
Crash ID: 5dc199ce255e6925

1. Open repro-pdf.html
2. Click on the button to open test.pdf link in new tab and click on pdf bubble as in "1.png" then after 5s the page will be changed as in 2.png
3. click on "DONE" button or Open in Adobe Reader link.

The problem is that if a tab is changed location or closed via JavaScript, bubble isn't closing and is stays open.

Adding Merge-Triage label for tracking purposes.

Once your fix had sufficient bake time (on canary, dev as appropriate), please nominate your fix for merge by adding the Merge-Requested label.

When your merge is approved by the release manager, please start merging with higher milestone label first. Make sure to re-request merge for every milestone in the label list. You can get branch information on

Your fix is very close to the branch point. After the branch happens, please make sure to check if your fix is in.

This can just roll in M41, no need to merge this medium severity bug.

Congratulations - $500 for this report.

Notes from panel: Use-after-free though required a very unique set of interactions that seems unlikely, which is why the reward amount is lower than usual.

Even though this fix rolled out with a patch to M41, we'll mention it in our release notes for M42.

Processing via our e-payment system can take up to two weeks, but the reward should be on its way to you. Thanks again for your help!
