Detection & IOCsextracted from sources · hover to see the quote
- →Trigger is a crafted SWF file; inspect SWF files for anomalous slab/solid-slab graphics element structures that may exploit out-of-range pointer arithmetic in the graphics rendering path. ↗
- →Monitor Flash Player processes (standalone player and Microsoft Edge) for heap or stack corruption crashes during SWF rendering, particularly in slab rendering routines. ↗
- →Flag delivery of SWF files that trigger the slab/solid-slab graphics rendering code path; the vulnerability is exercised during graphics rendering of solid slab elements, distinct from blur or audio processing paths. ↗
- ·Affected versions are Adobe Flash Player 29.0.0.113 and earlier across all platforms (Windows, Macintosh, Linux, Chrome OS); exploitation requires the victim to open a specially crafted SWF file. ↗
- ·The PoC crash reliability varies by platform; most reliable in standalone Flash Player and Microsoft Edge, less so in other environments — detection based on crash telemetry may have lower fidelity on other platforms. ↗
