Version 1.6.57 [April 8, 2026]
6372+
Fixed CVE-2026-34757 (medium severity):
6373+
Use-after-free in `png_set_PLTE`, `png_set_tRNS` and `png_set_hIST`
6374+
leading to corrupted chunk data and potential heap information disclosure.
6375+
Also hardened the append-style setters (`png_set_text`, `png_set_sPLT`,
6376+
`png_set_unknown_chunks`) against a theoretical variant of the same
6377+
aliasing pattern.
6378+
(Reported by Iv4n <[email protected]>.)
6379+
Fixed integer overflow in rowbytes computation in read transforms.
