CVE-2026-12912
Published: June 29th, 2026
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).

| 26.3 | libtiff (4.6.0) | Not Affected | Code Not Reachable | The overflow in PixarLogDecode (tif_pixarlog.c) is only reachable when the application explicitly selects the PIXARLOGDATAFMT_8BITABGR output format by calling TIFFSetField(tif, TIFFTAG_PIXARLOGDATAFMT, PIXARLOGDATAFMT_8BITABGR).
