CVE-2007-3944: Multiple heap-based buffer overflows in the Perl Compatible Regular Expressions (PCRE) library in the JavaS...

Multiple heap-based buffer overflows in the Perl Compatible Regular Expressions (PCRE) library in the JavaScript engine in WebKit in Apple Safari 3 Beta before Update 3.0.3, and iPhone before 1.0.1, allow remote attackers to execute arbitrary code via certain JavaScript regular expressions. NOTE: this issue was originally reported only for MobileSafari on the iPhone. NOTE: it is not clear whether this stems from an issue in the original distribution of PCRE, which might already have a separate CVE identifier.

Security readout for executives and security teams

This is a 2007 browser memory-corruption issue affecting Apple Safari 3 Beta and early iPhone software. A malicious web page using crafted JavaScript regular expressions could trigger heap overflows and potentially run code. For most organizations, urgency is historical unless legacy Apple browsers or devices remain in use. Exposure appears limited to Apple Safari 3 Beta before Update 3.0.3 and iPhone before 1.0.1, based on the CVE description. Modern exposure is unlikely unless unsupported legacy devices, archived test systems, or old browser builds remain reachable by web content. Treat as high impact but usually low present-day urgency. Prioritize only if the organization still operates legacy Apple browser stacks, embedded test labs, or archival systems that can browse untrusted web content. Mitigation focus: Upgrade Safari 3 Beta to Update 3.0.3 or later where applicable.; Upgrade iPhone software to 1.0.1 or later where applicable.; Remove unsupported legacy Safari and early iPhone builds from production use..
