Xavier Roche discovered an infinite loop in the gdPngReadData()
function when processing a truncated PNG file (CVE-2007-2756). An
integer overflow has been discovered in the gdImageCreateTrueColor()
function (CVE-2007-3472). An error has been discovered in the function
gdImageCreateXbm() function (CVE-2007-3473). Unspecified
vulnerabilities have been discovered in the GIF reader (CVE-2007-3474).
An error has been discovered when processing a GIF image that has no
global color map (CVE-2007-3475). An array index error has been
discovered in the file gd_gif_in.c when processing images with an
invalid color index (CVE-2007-3476). An error has been discovered in
the imagearc() and imagefilledarc() functions when processing overly
large angle values (CVE-2007-3477). A race condition has been
discovered in the gdImageStringFTEx() function (CVE-2007-3478).
</p>
</description>
<impact type="normal">
<p>
A remote attacker could exploit one of these vulnerabilities to cause a
Denial of Service or possibly execute arbitrary code with the
privileges of the user running GD.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All GD users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.35"</code>
</resolution>
