Details

Xavier Roche discovered that libgd’s function for reading GIF image
data did not sufficiently verify its validity. Specially crafted GIF
images could cause an infinite loop which used up all available CPU
resources. Since libgd is often used in PHP and Perl web applications,
this could lead to a remote Denial of Service vulnerability.
