Windows 2003 Server - Denial of Service via Malformed PNG tEXt Chunk
Microsoft Windows Explorer (explorer.exe) allows user-assisted remote attackers to cause a denial of service (CPU consumption) via a certain PNG file with a large tEXt chunk that possibly triggers an integer overflow in PNG chunk size handling, as demonstrated by badlycrafted.png.
The LZW decoding in the gdImageCreateFromGifPtr function in the Thomas Boutell graphics draw (GD) library (aka libgd) 2.0.33 allows remote attackers to cause a denial of service (CPU consumption) via malformed GIF data that causes an infinite loop.
