Comment 2 Todd Cullum 2020-08-21 17:40:06 UTC
Flaw Summary:

If the size variable is not a multiple of 6, a heap buffer overflow -> out-of-bounds read could occur in the tiff12_print_page() routine of /devices/gdevtfnx.c. size is received from a printer device. This flaw could be exploited via a crafted PDF file input. The patch adds 5 to the size prior to heap allocation to avoid this.
