Insight
A buffer overflow was discovered in libgd2's font renderer. By tricking an application using libgd2 into rendering a specially crafted string with a JIS encoded font, a remote attacker could read heap memory or crash the application, leading to a denial of service. (CVE-2007-0455)
Xavier Roche discovered that libgd2 did not correctly validate PNG callback results. If an application were tricked into processing a specially crafted PNG image, it would monopolize CPU resources. Since libgd2 is often used in PHP and Perl web applications, this could lead to a remote denial of service. (CVE-2007-2756)
