Google on Thursday announced an update to the desktop version of its Chrome web browser, including security fixes for 36 vulnerabilities, 15 of which were designated as high severity.

In totally, the repairs are worth at least $70,000 in bug bounty rewards paid to external researchers. (Not all payout amounts were listed.) Some of the more serious errors were classified as private property access in V8, universal cross-site scripting in Blink, same-origin bypass in PDFium, out-of-bounds writes in Blink and PDFium, use-after-free in PDFium and V8, and local file disclosure in DevTools.

This newest stable-channel release – version 55.0.2883.75 for Windows, Mac and Linux – will roll out over the coming days and weeks, the company announced on its Chrome Releases blog page.
