Fuzzed inputs drove one check-one process to 2-6 GB (the 16 GB CI runner running two of them was killed every night). Three causes, each with a test: - lopdf (bootstrap inspector) sized PNG predictor rows from /Columns before reading data: /Columns 4294967295 allocated two 4 GiB rows. Vendored lopdf 0.45.0 refuses rows longer than the data (and uses saturating row widths); its load-time stream decoding also gets a 256 MiB limit (it had none). - hayro sized a tiling pattern's cell pixmap from /XStep x scale, bounded only by u16: a step far beyond /BBox allocated 2 GB. The vendored patch keeps the cell within 3000 px a side, lowering the resolution instead. - cos decoded cross-reference streams up to the general 1 GiB limit; they now stop at what 8,388,607 objects' rows can hold (~200 MB at most), and the section is reconstructed (logged) instead. On the nightly's seed (41) the worst captured input fell from 6.2 GB to 6 MB, and a 300 s fuzz run had no process above 300 MB (before: many at 2-5 GB).
