libpng `png_decompress_chunk()´ Integer Overflow Vulnerability

A vulnerability has been identified in libpng, which can be exploited by malicious people to potentially compromise an application using the library.

The vulnerability is caused due to an integer overflow error within the "png_decompress_chunk()" function (pngrutil.c) when uncompressing certain chunks, which can be exploited to cause a heap-based buffer overflow.

Successful exploitation may allow execution of arbitrary code but requires tricking the user into opening a specially crafted PNG file.
