The DecodeHSTSPreloadRaw function in net/http/transport_security_state.cc in Google Chrome before 43.0.2357.130 does not properly canonicalize DNS hostnames before making comparisons to HSTS or HPKP preload entries, which allows remote attackers to bypass intended access restrictions via a string that (1) ends in a . (dot) character or (2) is not entirely lowercase.

Security readout for executives and security teams

This old Chrome flaw could let a remote site bypass Chrome’s preloaded HSTS or HPKP protections by using hostname strings with uppercase characters or a trailing dot. That could weaken browser-enforced HTTPS or certificate restrictions for affected users. The source bundle does not show active exploitation. Exposure is limited to systems still running Google Chrome or Chromium builds older than 43.0.2357.130, including 2015-era distro packages referenced by vendor advisories. Modern managed browsers are unlikely to be exposed if routinely updated. Treat this as a legacy browser hygiene issue. It matters where obsolete Chrome or Chromium builds remain, but current evidence does not support emergency response for updated environments. Mitigation focus: Upgrade Chrome or Chromium to 43.0.2357.130 or later.; Apply relevant distro security updates from Ubuntu, Red Hat, openSUSE, Gentoo, or Debian.; Confirm enterprise browser management prevents legacy Chrome versions..
