The Portable Network Graphics library (libpng) contains a flaw that could introduce a remotely exploitable vulnerability.
The Portable Network Graphics (PNG) image format is used as an alternative to other image formats such as the Graphics Interchange Format (GIF). The libpng reference library is available for application developers to support the PNG image format.
A potential integer overflow error exists during a memory allocation within the png_handle_sPLT() function. While the code that contains this error introduces a dangerous condition, it is unclear what practical vulnerabilities it might present in applications using libpng.
The complete impact of this vulnerability is not yet known.
