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.

Exploit prediction (EPSS)

4.75% probability of exploitation in the next 30 days, higher than 92% of all scored CVEs.
