Application crash via unchecked zero divisors
Published Jul 15, 2021 · Updated Aug 3, 2024
Division by zero in Libvips 8.10.5 allows remote attackers to crash image-processing applications via a crafted image file. vips_eye_point squares height minus one and uses the result as a divisor, while vips_mask_point divides by half-width and half-height, without rejecting values that become zero. Exploitation requires an application or user to process attacker-controlled image data; the consequence is limited to service interruption.
