CVE-2007-2445 libpng vulnerability
Title: libpng vulnerability
Summary: libpng vulnerability
It was discovered that libpng did not correctly handle corrupted CRC
in grayscale PNG images. By tricking a user into opening a specially
crafted PNG, a remote attacker could cause the application using libpng
to crash, resulting in a denial of service.
Instructions: After a standard system upgrade you need to reboot your computer to
effect the necessary changes.

Discussion:
libpng10-1.0.26-1.fc6 has been released for Fedora Extras 6, which should
resolve this problem.
There is also a release libpng10-1.0.26-1.fc7.1 in Fedora 7 updates and
libpng10-1.0.26-1.fc8 for development.

CVE-2007-2445 libpng png_handle_tRNS flaw
"From: Glenn Randers-Pehrson
A security bug has been reported to mozilla.
It seems that a grayscale image with a malformed (bad CRC) tRNS chunk
will crash libpng and mozilla. In my experience it also brought down
my Windows display manager.
The reason is that png_ptr->num_trans is set to 1 and then there is
an error return after checking the CRC, so the trans[] array is never
allocated. Since png_ptr->num_trans is nonzero, libpng tries to use
the array later. Here is the fix, thanks to Mats Palmgren:
At line 1316 of pngrutil.c, change
if (png_crc_finish(png_ptr, 0))
return;
to
if (png_crc_finish(png_ptr, 0))
{
png_ptr->num_trans = 0;
return;
}
Libpng-1.2.17rc1 does not contain this fix."
