| CVE-2008-1382 | 2 Libpng, Redhat | 2 Libpng, Enterprise Linux | 2026-04-23 | N/A |
| libpng 1.0.6 through 1.0.32, 1.2.0 through 1.2.26, and 1.4.0beta01 through 1.4.0beta19 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PNG file with zero length "unknown" chunks, which trigger an access of uninitialized memory. | ||||
| CVE-2007-5269 | 2 Libpng, Redhat | 2 Libpng, Enterprise Linux | 2026-04-23 | N/A |
| Certain chunk handlers in libpng before 1.0.29 and 1.2.x before 1.2.21 allow remote attackers to cause a denial of service (crash) via crafted (1) pCAL (png_handle_pCAL), (2) sCAL (png_handle_sCAL), (3) tEXt (png_push_read_tEXt), (4) iTXt (png_handle_iTXt), and (5) ztXT (png_handle_ztXt) chunking in PNG images, which trigger out-of-bounds read operations. | ||||
| CVE-2007-5267 | 1 Libpng | 1 Libpng | 2026-04-23 | N/A |
| Off-by-one error in ICC profile chunk handling in the png_set_iCCP function in pngset.c in libpng before 1.2.22 beta1 allows remote attackers to cause a denial of service (crash) via a crafted PNG image, due to an incorrect fix for CVE-2007-5266. | ||||
| CVE-2008-3964 | 1 Libpng | 1 Libpng | 2026-04-23 | N/A |
| Multiple off-by-one errors in libpng before 1.2.32beta01, and 1.4 before 1.4.0beta34, allow context-dependent attackers to cause a denial of service (crash) or have unspecified other impact via a PNG image with crafted zTXt chunks, related to (1) the png_push_read_zTXt function in pngread.c, and possibly related to (2) pngtest.c. | ||||
| CVE-2008-6218 | 1 Libpng | 1 Libpng | 2026-04-23 | N/A |
| Memory leak in the png_handle_tEXt function in pngrutil.c in libpng before 1.2.33 rc02 and 1.4.0 beta36 allows context-dependent attackers to cause a denial of service (memory exhaustion) via a crafted PNG file. | ||||
| CVE-2007-5268 | 2 Canonical, Libpng | 2 Ubuntu Linux, Libpng | 2026-04-23 | N/A |
| pngrtran.c in libpng before 1.0.29 and 1.2.x before 1.2.21 use (1) logical instead of bitwise operations and (2) incorrect comparisons, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG image. | ||||
| CVE-2009-2042 | 2 Libpng, Redhat | 2 Libpng, Enterprise Linux | 2026-04-23 | N/A |
| libpng before 1.2.37 does not properly parse 1-bit interlaced images with width values that are not divisible by 8, which causes libpng to include uninitialized bits in certain rows of a PNG file and might allow remote attackers to read portions of sensitive memory via "out-of-bounds pixels" in the file. | ||||
| CVE-2007-5266 | 1 Libpng | 1 Libpng | 2026-04-23 | N/A |
| Off-by-one error in ICC profile chunk handling in the png_set_iCCP function in pngset.c in libpng before 1.0.29 beta1 and 1.2.x before 1.2.21 beta1 allows remote attackers to cause a denial of service (crash) via a crafted PNG image that prevents a name field from being NULL terminated. | ||||
| CVE-2009-0040 | 7 Apple, Debian, Fedoraproject and 4 more | 10 Iphone Os, Mac Os X, Debian Linux and 7 more | 2026-04-23 | N/A |
| The PNG reference library (aka libpng) before 1.0.43, and 1.2.x before 1.2.35, as used in pngcrush and other applications, allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file that triggers a free of an uninitialized pointer in (1) the png_read_png function, (2) pCAL chunk handling, or (3) setup of 16-bit gamma tables. | ||||
| CVE-2008-5907 | 2 Debian, Libpng | 2 Debian Linux, Libpng | 2026-04-23 | N/A |
| The png_check_keyword function in pngwutil.c in libpng before 1.0.42, and 1.2.x before 1.2.34, might allow context-dependent attackers to set the value of an arbitrary memory location to zero via vectors involving creation of crafted PNG files with keywords, related to an implicit cast of the '\0' character constant to a NULL pointer. NOTE: some sources incorrectly report this as a double free vulnerability. | ||||
| CVE-2026-3713 | 1 Libpng | 1 Libpng | 2026-04-22 | 5.3 Medium |
| A flaw has been found in pnggroup libpng up to 1.6.55. Affected by this vulnerability is the function do_pnm2png of the file contrib/pngminus/pnm2png.c of the component pnm2png. This manipulation of the argument width/height causes heap-based buffer overflow. The attack is restricted to local execution. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet. | ||||
| CVE-2026-22695 | 1 Libpng | 1 Libpng | 2026-04-18 | 6.1 Medium |
| 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 | 1 Libpng | 1 Libpng | 2026-04-18 | 6.8 Medium |
| 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-2026-25646 | 2 Libpng, Pnggroup | 2 Libpng, Libpng | 2026-04-17 | 8.1 High |
| LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is fixed in 1.6.55. | ||||
| CVE-2004-0421 | 4 Libpng, Openpkg, Redhat and 1 more | 7 Libpng, Openpkg, Enterprise Linux and 4 more | 2026-04-16 | N/A |
| The Portable Network Graphics library (libpng) 1.0.15 and earlier allows attackers to cause a denial of service (crash) via a malformed PNG image file that triggers an error that causes an out-of-bounds read when creating the error message. | ||||
| CVE-2026-33416 | 2 Libpng, Pnggroup | 2 Libpng, Libpng | 2026-04-03 | 7.5 High |
| 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 | 2 Libpng, Pnggroup | 2 Libpng, Libpng | 2026-04-03 | 7.6 High |
| 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-2025-28164 | 1 Libpng | 1 Libpng | 2026-03-04 | 5.5 Medium |
| Buffer Overflow vulnerability in libpng 1.6.43-1.6.46 allows a local attacker to cause a denial of service via png_create_read_struct() function. | ||||
| CVE-2025-28162 | 1 Libpng | 1 Libpng | 2026-02-06 | 5.5 Medium |
| Buffer Overflow vulnerability in libpng 1.6.43-1.6.46 allows a local attacker to cause a denial of service via the pngimage with AddressSanitizer (ASan), the program leaks memory in various locations, eventually leading to high memory usage and causing the program to become unresponsive | ||||
| CVE-2025-66293 | 1 Libpng | 1 Libpng | 2025-12-16 | 7.1 High |
| 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. | ||||
