Descriptions

The TIFFFdOpen function in tif_unix.c in LibTIFF 4.0.10 has a memory leak, as demonstrated by pal2rgb.

La función TIFFdOpen en tif_unix.c en LibTIFF 4.0.10 tiene una fuga de memoria, tal y como queda demostrado con pal2rgb.

It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
