A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).

Solution

No solution given by the vendor.


Workaround

To mitigate this issue, applications processing untrusted TIFF images should avoid explicitly configuring `PIXARLOGDATAFMT_8BITABGR` when decoding PixarLog-compressed TIFF images with three samples per pixel. This specific combination of output format and samples per pixel is required to trigger the heap-based buffer overflow.
