Out-of-bounds heap buffer reads in libpng versions prior to 1.6.55 can be triggered through the png_set_quantize() function when processing specially crafted PNG images with specific palette configurations, potentially causing denial of service or information disclosure. Public exploit code exists for this vulnerability, affecting applications that use libpng to process untrusted PNG files. A patch is available in version 1.6.55 and later.
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. [CVSS 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 [CVSS 5.5 MEDIUM]
Libpng versions 1.6.26 through 1.6.53 contain an integer truncation flaw in the simplified write API functions that triggers a heap buffer over-read when processing images with negative row strides or strides exceeding 65535 bytes. Local attackers can exploit this to read sensitive heap memory, potentially disclosing application data. No patch is currently available; users should avoid processing untrusted PNG images with these vulnerable libpng versions.
Libpng versions 1.6.51-1.6.53 contain a heap buffer over-read in the simplified API function png_image_finish_read when processing interlaced 16-bit PNG images with 8-bit output and non-minimal row stride, allowing local attackers to read out-of-bounds memory through a malicious image file. Public exploit code exists for this regression, which was introduced by a previous security fix. Upgrade to version 1.6.54 to remediate.
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.
LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Rated high severity (CVSS 7.1), this vulnerability is no authentication required, low attack complexity. Public exploit code available.

LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Rated medium severity (CVSS 6.1), this vulnerability is no authentication required, low attack complexity. This Out-of-bounds Read vulnerability could allow attackers to read data from memory outside the intended buffer boundaries.
