Descripción técnica

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 `ANMF` frame metadata. In `sail_codec_load_init_v8_webp()` in `src/sail-codecs/webp/webp.c`, `WebPDemuxGetI` with `WEBP_FF_CANVAS_WIDTH` can return a zero `image_local->width`, which is then used as a divisor when calculating `bytes_per_pixel` from the image row size. The division happens before frame decoding and before generic image skeleton validation in `src/sail/sail_advanced.c`, 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.

——2Schroedinger libschroedinger through 1.0.11 contains a divide by zero vulnerability that allows attackers to crash applications by supplying a zero slice_bytes_denom or slice count in a Dirac stream. Attackers can provide a crafted low-delay picture parsed by schro_decoder_parse_transform_parameters and schro_decoder_parse_lowdelay_transform_data to trigger a SIGFPE and cause denial of service.7d CVE-2026-1120135.5 MED

——1libtta through 2.3 contains a divide-by-zero vulnerability in tta_decoder_init_get_info() that allows attackers to crash applications by supplying an unvalidated zero sample rate. Attackers can craft a .tta file with a recomputed header CRC32 that triggers SIGFPE, crashing applications including the bundled tta console tool.9d CVE-2025-556535.5 MED

——2GPAC MP4Box v2.4 was discovered to contain a floating point exception in the gf_parse_lfrac function (utils/error.c). Processing a crafted MP4 file containing a zero-denominator fraction string causes gf_parse_lfrac() to divide by zero, terminating the process with SIGFPE.14h CVE-2026-1106055.5 MED

——6libschrift through 0.10.2 contains a divide by zero vulnerability that allows attackers to crash applications by supplying a font with unitsPerEm of 0 in the head table. Attackers can provide a crafted TrueType font whose NaN glyph coordinates bypass clip_points(), causing an out-of-bounds raster read in draw_line() during sft_render() and crashing the process.2d CVE-2026-1071596.5 MED
