A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
libgd2-noxpm 2.0.33-2ubuntu5.2
libgd2-xpm 2.0.33-2ubuntu5.2
Ubuntu 6.10:
libgd2-noxpm 2.0.33-4ubuntu2.1
libgd2-xpm 2.0.33-4ubuntu2.1
Ubuntu 7.04:
libgd2-noxpm 2.0.34~rc1-2ubuntu1.1
libgd2-xpm 2.0.34~rc1-2ubuntu1.1
After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
Details follow:
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)
