    CVE-2025-66293:
    LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. Prior to 1.6.52, an out-of-bounds read vulnerability in libpng's     simplified API allows reading up to 1012 bytes beyond the png_sRGB_base[512] array when processing valid     palette PNG images with partial transparency and gamma correction. The PNG files that trigger this     vulnerability are valid per the PNG specification; the bug is in libpng's internal state management.
    Upgrade to libpng 1.6.52 or later.

    CVE-2026-22695:
    LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. From 1.6.51 to 1.6.53, there is a heap buffer over-read in the     libpng simplified API function png_image_finish_read when processing interlaced 16-bit PNGs with 8-bit     output format and non-minimal row stride. This is a regression introduced by the fix for CVE-2025-65018.
    This vulnerability is fixed in 1.6.54.

    CVE-2026-22801:
    LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. From 1.6.26 to 1.6.53, there is an integer truncation in the libpng     simplified write API functions png_write_image_16bit and png_write_image_8bit causes heap buffer over-read     when the caller provides a negative row stride (for bottom-up image layouts) or a stride exceeding 65535     bytes. The bug was introduced in libpng 1.6.26 (October 2016) by casts added to silence compiler warnings     on 16-bit systems. This vulnerability is fixed in 1.6.54.

    CVE-2026-23865:
    An integer overflow in the tt_var_load_item_variation_store function of the Freetype library in versions     2.13.2 and 2.13.3 may allow for an out of bounds read operation when parsing HVAR/VVAR/MVAR tables in     OpenType variable fonts. This issue is fixed in version 2.14.2.

    CVE-2026-26740:
    Buffer Overflow vulnerability in giflib v.5.2.2 allows a remote attacker to cause a denial of service via     the EGifGCBToExtension overwriting an existing Graphic Control Extension block without validating its     allocated size.

    CVE-2026-33416:
    LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. In versions 1.2.1 through 1.6.55, `png_set_tRNS` and `png_set_PLTE`     each alias a heap-allocated buffer between `png_struct` and `png_info`, sharing a single allocation across     two structs with independent lifetimes. The `trans_alpha` aliasing has been present since at least libpng     1.0, and the `palette` aliasing since at least 1.2.1. Both affect all prior release lines `png_set_tRNS`     sets `png_ptr->trans_alpha = info_ptr->trans_alpha` (256-byte buffer) and `png_set_PLTE` sets     `info_ptr->palette = png_ptr->palette` (768-byte buffer). In both cases, calling `png_free_data` (with     `PNG_FREE_TRNS` or `PNG_FREE_PLTE`) frees the buffer through `info_ptr` while the corresponding `png_ptr`     pointer remains dangling. Subsequent row-transform functions dereference and, in some code paths, write to     the freed memory. A second call to `png_set_tRNS` or `png_set_PLTE` has the same effect, because both     functions call `png_free_data` internally before reallocating the `info_ptr` buffer. Version 1.6.56 fixes     the issue.

    CVE-2026-33636:
    LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. In versions 1.6.36 through 1.6.55, an out-of-bounds read and write     exists in libpng's ARM/AArch64 Neon-optimized palette expansion path. When expanding 8-bit paletted rows     to RGB or RGBA, the Neon loop processes a final partial chunk without verifying that enough input pixels     remain. Because the implementation works backward from the end of the row, the final iteration     dereferences pointers before the start of the row buffer (OOB read) and writes expanded pixel data to the     same underflowed positions (OOB write). This is reachable via normal decoding of attacker-controlled PNG     input if Neon is enabled. Version 1.6.56 fixes the issue.

    CVE-2026-34268:
