### Summary Validate the `EMR_EXTCREATEPEN` style entry count before allocating the dash pattern array. ### Changes * Add `HemfPicture.safelyAllocateCheck(numStyleEntries)` before allocating the dash pattern array. * Reuse the existing HEMF allocation validation mechanism already used in related parser paths. * Reject oversized style entry counts before attempting memory allocation. ### Why * `numStyleEntries` is read from EMF input and directly controls array allocation size. * A malformed record can request an excessively large allocation, leading to resource exhaustion or allocation failures. * This change ensures allocation limits are enforced consistently across HEMF record parsers. ### Impact * No behavior change for valid EMF files. * Oversized or malformed inputs now fail through the existing validation path instead of attempting allocation. * Aligns `EMR_EXTCREATEPEN` with the recent HEMF allocation-hardening updates. -- This is an automated message from the Apache Git Service.
