Description Sam Fowler 2018-10-02 05:10:53 UTC 
The function t2p_write_pdf in tiff2pdf.c in LibTIFF 4.0.9 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted TIFF file, a similar issue to CVE-2017-9935.
