Comment 2 Todd Cullum 2020-08-20 15:51:54 UTC
Flaw summary:

In the driver /devices/gdev3852.c, a high resolution file could overflow the stack buffer because there was no check for size in jetp3852_print_page(), resulting in denial of service. The patch ensures that if the scanline size is larger than the buffer, it will error out instead of overflow the stack.

Comment 4 Todd Cullum 2020-08-20 16:56:19 UTC
