Name of the Vulnerable Software and Affected Versions libvips versions prior to 8.18.3
Description A crafted many-band TIFF image processed through the VipsForeignLoadTiff function can bypass scanline validation in libvips/iofuncs/image.c, leading to an integer overflow in the vips image sanity() function. This results in a buffer-region calculation that allows access to attacker-controlled negative offsets in mmap-resident allocations. This behavior can lead to the reading or writing of other image data, potential data disclosure via uncompressed .v output, and process crashes.
Recommendations Update to version 8.18.3.
