libpng png_decompress_chunk() buffer overflow
| libpng-pngdecompresschunk-bo (27468) |  High Risk |
Description:
The libpng Portable Network Graphics (PNG) library is vulnerable to a buffer overflow, caused by improper bounds checking by the png_decompress_chunk() function in the pngrutil.c routine. By sending a specially-crafted PNG image containing malformed compressed data, a remote attacker could overflow a buffer and possibly execute arbitrary code on the system or cause the application linked to libpng to crash.
