Check for the version of the gd packages

Detailed Explanation for this Vulnerability Test

Updated gd packages that fix security issues with overflow in various

it could cause ImageMagick to execute arbitrary code when processing the
image. The Common Vulnerabilities and Exposures project ( has
assigned the name CVE-2004-0990 to these issues.

While researching the fixes to these overflows, additional buffer overflows
were discovered in calls to gdMalloc. The Common Vulnerabilities and
Exposures project ( has assigned the name CVE-2004-0941 to

backported security patch, and are not vulnerable to these issues.
