- CVE-2026-40930 affecting package gdal 3.6.3-2
- Details
-
LIBPNG is a reference library for use in applications that process PNG (Portable Network Graphics) raster image files. In version 1.8.0, three inter-frame chunk discard paths in the push-mode APNG parser clear the chunk-header flag without consuming the chunk body and CRC, allowing attacker-controlled bytes inside an ignored ancillary chunk to be reinterpreted as a fresh chunk header on the next call to
png_process_data. Commit faf06924688b62d7c1654b5ceddedbde66ffadb4 fixes the issue. - References
