+Subject: [PATCH] MD2: compute the frame-table bounds check in 64-bit (integer
+ overflow) (#6963)
+
+The header validation rejects out-of-file offsets with
+    offsetFrames + numFrames * frameSize >= fileSize
+but numFrames is an attacker-controlled uint32 and frameSize is an unsigned
+int that grows with numVertices (another uint32 field), so the product is a
+32-bit multiply that can wrap. The AI_MAX_ALLOC guards above bound numFrames
+only against sizeof(MD2::Frame) (~44 bytes, ceiling ~48M), while frameSize can
+be far larger (e.g. numVertices=1014 -> 4096), so numFrames ~= 2^20 already
+wraps numFrames*frameSize to a small value and the check passes. The frame
+vertices are then read out of bounds (heap OOB read / info leak).
+
+Compute frameSize and the four offset+count*size checks in 64-bit so the
+products cannot wrap. Reachable from Assimp::Importer::ReadFile() on a crafted
+.md2 (MD2 is default-enabled). Confirmed with AddressSanitizer
+(heap-buffer-overflow READ in InternReadFile); valid .md2 files
+(dolphin/horse/flag/faerie) still load unchanged.
