BlueSharpieOfDoom writes "Whitedust has an interesting article posted about the new zlib buffer overflow. It affects countless software applications, even on Microsoft Windows. Some of the most affected application are those that are able to use the PNG graphic format, as zlib is wildely used in compression of PNG images. Zlib was also in the news in 2002 because of a flaw found in the way it handled memory allocation. The new hole could allow remote attackers to crash the vulnerable program or even the possiblity of executing arbitrary code."
