Security readout for executives and security teams
CVE-2011-3336 is a denial-of-service issue in the BSD libc regular expression compiler. On affected Apple macOS systems through 2011, specially crafted regular expression handling could exhaust stack memory and crash the process using that library. Exposure is most likely on obsolete Apple macOS systems from 2011 or earlier, especially where software compiles untrusted regular expressions. The bundle does not prove exposure for modern macOS or provide a complete affected-version matrix. Treat this as legacy-risk cleanup, not an emergency zero-day response. Prioritize if old macOS systems remain exposed or support critical workflows that can be disrupted by process crashes. Mitigation focus: Inventory and retire unsupported macOS systems from 2011 or earlier.; Check Apple guidance for supported updates or replacement paths.; Reduce acceptance of untrusted regular expression patterns on affected systems..
