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).

<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>
