Check for the version of the libpng package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory MDKSA-2002:049 (libpng). 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 permiting a possible hacker 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'.
