xterm through Patch 370, when Sixel support is enabled, allows attackers to trigger a buffer overflow in set_sixel in graphics_sixel.c via crafted text.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
