Details

libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.0 and earlier, a crafted image sequence with a 2x2 primary plane and a 256x256 auxiliary alpha plane can cause attacker-controlled heap corruption during a normal decode and re-encode workflow. TrackVisual::decodenextimagesample() calls transferchannelfromimageas() without checking that the auxiliary alpha dimensions match the main frame. The resulting inconsistent image reaches heiftrackdecodenextimage() and then heifcontextencodeimage(). In uncencoder::encode(), uncencodercomponentinterleave::encodetile() sizes its buffer with computetiledatasizebytes() using the primary dimensions but copies each component using its actual plane dimensions. The oversized alpha plane is therefore copied beyond the allocation, causing an out-of-bounds write; the inverse size mismatch can also produce an out-of-bounds read. This issue is fixed in version 1.23.1.
