Описание
LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From version 1.6.0 to before 1.6.51, there is a heap buffer overflow vulnerability in the libpng simplified API function png_image_finish_read when processing 16-bit interlaced PNGs with 8-bit output format. Attacker-crafted interlaced PNG files cause heap writes beyond allocated buffer bounds. This issue has been patched in version 1.6.51.
A buffer overflow flaw has been discovered in libpng. There is a heap buffer overflow vulnerability in the libpng simplified API function png_image_finish_read when processing 16-bit interlaced PNGs with 8-bit output format. Attacker-crafted interlaced PNG files cause heap writes beyond allocated buffer bounds.
Отчет
This vulnerability is rated Important for Red Hat products. A heap buffer overflow exists in the libpng library's png_image_finish_read function when processing specially crafted 16-bit interlaced PNG images with an 8-bit output format. Successful exploitation requires a user or an automated system to process a malicious PNG file, which could lead to application crashes or arbitrary code execution. java-*-openjdk-headless packages do not contain libsplashscreen.so, hence are not affected.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
