→Trigger involves loading a crafted PNG file via a Flash SWF (LoadImage.swf) — monitor for SWF files dynamically loading external PNG resources, particularly with suspicious query-string-style parameters appended to the SWF URL. ↗
→Vulnerability resides in Adobe Flash Player's PNG image parser — inspect Flash content that loads or decodes PNG images for out-of-bounds read/memory corruption behaviour. ↗
→Flag Adobe Flash Player at version 25.0.0.171 or earlier as vulnerable; prioritise patching or blocking Flash execution in browsers. ↗

·The PoC exploit package (42248.zip) contains the proof-of-concept SWF and PNG files; treat any instance of these artefacts in the environment as a strong indicator of exploitation attempts rather than legitimate use. ↗
