Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the _decodeAsRGBA and _decodeTile functions in src/libImaging/TiffDecode.c when processing a TIFF image whose unpacker row size exceeds the libtiff-decoded row size. An attacker can supply a malformed TIFF file that triggers a read buffer overflow on the last row of a decoded block or tile, leading to out-of-bounds memory access and potential information disclosure or a crash.
