Untrusted search path vulnerability in Mozilla Network Security Services (NSS), as used in Google Chrome before 17 on Windows and Mac OS X, might allow local users to gain privileges via a Trojan horse pkcs11.txt file in a top-level directory.

Security readout for executives and security teams

This CVE describes a file-search behavior in Mozilla NSS used by Google Chrome before 17 on Windows and Mac OS X. A local user could potentially influence Chrome by placing a malicious pkcs11.txt file in a top-level directory. The record includes no CVSS score and notes the vendor did not treat it as a security bug. Exposure is most plausible on legacy endpoints running Google Chrome before 17 on Windows or Mac OS X. Linux distribution advisories are referenced, but the bundle does not provide enough detail to name exact openSUSE package exposure or affected NSS versions. Treat this as a legacy exposure cleanup item, not an emergency based on available evidence. Priority rises if old Chrome or NSS-dependent packages remain on managed systems where local users can write to shared top-level directories. Mitigation focus: Retire or update any Chrome installations older than version 17.; Review referenced vendor advisories for applicable NSS or browser package updates.; Restrict low-privileged write access to top-level directories on managed endpoints..
