Description Josh Bressers 2006-04-24 15:35:29 EDT
X.Org buffer overflow

Bart Massey, a X.Org user reported that "When running rendertest from
XCB xcb/xcb-demo, the Xorg X server crashes partway through.  100%
reproducible on a wide variety of graphics architectures".

The upstream bug for this issue can be found here:
https://bugs.freedesktop.org/show_bug.cgi?id=6642

The problem, analyzed by Eric Anholt is a typo in render/mitri.c,
which was incorrectly calculating the size of a buffer.
