  "description": "SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to version 1.0.2, the built-in WebP decoder can crash during loader initialization when processing a malformed animated WebP file with inconsistent container or \u0060ANMF\u0060 frame metadata. In \u0060sail_codec_load_init_v8_webp()\u0060 in \u0060src/sail-codecs/webp/webp.c\u0060, \u0060WebPDemuxGetI\u0060 with \u0060WEBP_FF_CANVAS_WIDTH\u0060 can return a zero \u0060image_local-\u003Ewidth\u0060, which is then used as a divisor when calculating \u0060bytes_per_pixel\u0060 from the image row size. The division happens before frame decoding and before generic image skeleton validation in \u0060src/sail/sail_advanced.c\u0060, causing an arithmetic fault and process termination. Applications accepting untrusted WebP images can consequently suffer denial of service; builds must include the affected WebP codec. This issue is fixed in version 1.0.2.",
