The OneClickSigninHelper::ShowInfoBarIfPossible function in browser/ui/sync/one_click_signin_helper.cc in Google Chrome before 31.0.1650.63 uses an incorrect URL during realm validation, which allows remote attackers to conduct session fixation attacks and hijack web sessions by triggering improper sync after a 302 (aka Found) HTTP status code.

Security readout for executives and security teams

CVE-2013-6634 is an old Google Chrome flaw that could let a remote attacker interfere with sign-in synchronization after a redirect and potentially fixate or hijack a web session. The source bundle indicates Chrome before 31.0.1650.63 was affected. No CVSS score or active exploitation evidence is provided. Exposure is most likely limited to legacy Google Chrome or Chromium builds older than 31.0.1650.63, including old downstream distro packages. Modern managed browsers should not be exposed if normal browser update controls are functioning. This is not a current emergency based on the supplied evidence, but it is a hygiene risk if legacy browsers remain in use. Prioritize confirmation through endpoint inventory and remove obsolete browser builds. Mitigation focus: Ensure Chrome or Chromium is newer than 31.0.1650.63.; Remove unsupported legacy Chrome or Chromium builds from managed assets.; Review Debian and openSUSE advisories if relying on distro browser packages..
