The counterToCSSValue function in CSSComputedStyleDeclaration.cpp in the Cascading Style Sheets (CSS) implementation in WebCore in WebKit before r82222, as used in Google Chrome before 11.0.696.43 and other products, does not properly handle access to the (1) counterIncrement and (2) counterReset attributes of CSSStyleDeclaration data provided by a getComputedStyle method call, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted JavaScript code.

Security readout for executives and security teams

This is an old WebKit browser crash flaw. A malicious web page could use crafted JavaScript and CSS computed-style access to crash affected browsers, including Google Chrome versions before 11.0.696.43. Sources describe denial of service, not data theft or code execution. Exposure is mainly legacy systems running obsolete WebKit-based browsers or embedded browser components from the affected era. Modern managed browsers should not be exposed if updates are current. Low priority for modern environments, but worth closing if legacy browsers or embedded WebKit runtimes remain in production. The documented impact is browser denial of service, not confirmed system compromise. Mitigation focus: Upgrade affected Chrome installations to 11.0.696.43 or later.; Apply vendor updates for WebKit-based products that incorporated WebKit r82222 or later.; Retire unsupported browsers and embedded WebKit runtimes from managed environments..
