Integer overflow in the PCRE regular expression compiler (JavaScriptCore/pcre/pcre_compile.cpp) in Apple WebKit, as used in Safari before 3.1.1, allows remote attackers to execute arbitrary code via a regular expression with large, nested repetition counts, which triggers a heap-based buffer overflow.

Security readout for executives and security teams

CVE-2008-1026 is an old Apple Safari/WebKit flaw that could let a malicious web page run code on a user's machine. The issue is in WebKit's PCRE regular expression compiler and affects Safari before 3.1.1. The supplied sources do not show current active exploitation. Exposure is mainly legacy Safari installations older than 3.1.1. The bundle does not establish other affected products beyond Apple WebKit as used in Safari. Modern fleets are likely exposed only if obsolete browsers remain on managed, kiosk, lab, or archival systems. Prioritize only where legacy Safari exists. The business risk is high on affected hosts because exploitation could mean code execution through browsing, but urgency is bounded by whether obsolete Safari remains in the environment. Mitigation focus: Upgrade Safari to 3.1.1 or later where applicable.; Remove unsupported legacy Safari versions from managed systems.; Consult Apple guidance for affected historical platforms..
