Mandriva Linux Security Advisory 2009-051 - A number of vulnerabilities have been found and corrected in libpng. Fixed 1-byte buffer overflow in pngpread.c. This was allready fixed in Mandriva Linux 2009.0. Fix the function png_check_keyword() that allowed setting arbitrary bytes in the process memory to 0. Fix a potential DoS (Denial of Service) or to potentially compromise an application using the library. The updated packages have been patched to prevent this.
