The png_handle_cHRM function in pngrutil.c in libpng 1.5.4, when color-correction support is enabled, allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a malformed PNG image containing a cHRM chunk associated with a certain zero value.

The sPLT chunk handling code (png_set_sPLT function in pngset.c) in libpng 1.0.6 through 1.2.12 uses a sizeof operator on the wrong data type, which allows context-dependent attackers to cause a denial of service (crash) via malformed sPLT chunks that trigger an out-of-bounds read.

Buffer overflow in the png_decompress_chunk function in pngrutil.c in libpng before 1.2.12 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via unspecified vectors related to "chunk error processing," possibly involving the "chunk_name".

Heap-based buffer overflow in the alpha strip capability in libpng 1.2.7 allows context-dependent attackers to cause a denial of service (crash) when the png_do_strip_filler function is used to strip alpha channels out of the image.

Multiple buffer overflows in libpng 1.2.5 and earlier, as used in multiple products, allow remote attackers to execute arbitrary code via malformed PNG images in which (1) the png_handle_tRNS function does not properly validate the length of transparency chunk (tRNS) data, or the (2) png_handle_sBIT or (3) png_handle_hIST functions do not perform sufficient bounds checking.

Multiple integer overflows in the (1) png_read_png in pngread.c or (2) png_handle_sPLT functions in pngrutil.c or (3) progressive display image reading capability in libpng 1.2.5 and earlier allow remote attackers to cause a denial of service (application crash) via a malformed PNG image.

Portable Network Graphics (PNG) library libpng 1.2.5 and earlier does not correctly calculate offsets, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a buffer overflow attack on the row buffers.

Buffer overflow in libpng 1.0.12-3.woody.2 and libpng3 1.2.1-1.1.woody.2 on Debian GNU/Linux 3.0, and other operating systems, may allow attackers to cause a denial of service and possibly execute arbitrary code, a different vulnerability than CVE-2002-0728.

Buffer overflow in the progressive reader for libpng 1.2.x before 1.2.4, and 1.0.x before 1.0.14, allows attackers to cause a denial of service (crash) via a PNG data stream that has more IDAT data than indicated by the IHDR chunk.
