MDKSA-2002:022: zlib |

Check for the version of the zlib package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory MDKSA-2002:022 (zlib). Matthias Clasen found a security issue in zlib that, when provided with certain input, causes zlib to free an area of memory twice. This 'double free' bug can be used to crash any programs that take untrusted compressed input, such as web browsers, email clients, image viewing software, etc. This vulnerability can be used to perform Denial of Service attacks and, quite possibly, the execution of arbitrary code on the affected system. MandrakeSoft has published two advisories concerning this incident: MDKSA-2002:022 - zlib MDKSA-2002:023 - packages containing zlib The second advisory contains additional packages that bring their own copies of the zlib source, and as such need to be fixed and rebuilt. Updating the zlib library is sufficient to protect those programs that use the system zlib, but the packages as noted in MDKSA-2002:023 will need to be updated for those packages that do not use the system zlib.
