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 crafted PFR1 chunk that leads to an unexpected sign extension and an invalid pointer dereference, a different vulnerability than CVE-2011-0569.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
