Package name libpng Date August 13th, 2002 Advisory ID MDKSA-2002:049 Affected versions 7.1, 7.2, 8.0, 8.1, 8.2, CS1.0 Synopsis Updated libpng packages fix buffer overflow

Problem Description

A buffer overflow was found in the in the progressive reader of the PNG
library when the PNG datastream contains more IDAT data than indicated
by the IHDR chunk. These deliberately malformed datastreams would
crash applications thus potentially allowing an attacker to execute
malicious code. Many programs make use of the PNG libraries, including
web browsers. This overflow is corrected in versions 1.0.14 and 1.2.4
of the PNG library.

In order to have the system utilize the upgraded packages after the
upgrade, you must restart all running applications that are linked to
libpng. You can obtain this list by executing "lsof|grep libpng" or
"fuser -v /usr/lib/libpng.so".
