CVE-2011-0569 — Improper Restriction of Operations within the Bounds of a Memory Buffer in Adobe Shockwave Player

The Font Xtra.x32 module in Adobe Shockwave Player before 11.5.9.620 allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via a PFR1 chunk containing an invalid size value that leads to an unexpected sign extension and a buffer overflow, a different vulnerability than CVE-2011-0556.
