Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the tdsc_parse_tdsf function. An attacker can achieve heap corruption and potentially execute arbitrary code by supplying a crafted AVI file that manipulates frame dimensions across TDSF frames, leading tdsc_blit and tdsc_yuv2rgb to write attacker-controlled pixel data beyond the end of the reference frame buffer.
