Technical details
The vulnerability is a heap buffer overflow (CWE-787) in the r_readc() function within src/blocks/fromswf.c that occurs during SWF RECT header parsing. The function writes bytes into a fixed 9-byte rect[] buffer indexed by rectlen without bounds checking; legitimate RECT structures can require up to 17 bytes, and truncated streams cause unbounded writes up to ~199 bytes past the buffer. An attacker supplies a crafted SWF file with a malformed RECT header to trigger the overflow, causing denial of service at minimum.
