CVE-2017-9935 Memory corruption in n/a

What is CVE-2017-9935?

CVE-2017-9935 is a high-severity memory corruption vulnerability in Canonical Ubuntu Linux, published on 26 Jun 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

Official description

In LibTIFF 4.0.8, there is a heap-based buffer overflow in the t2p_write_pdf function in tools/tiff2pdf.c. This heap overflow could lead to different damages. For example, a crafted TIFF document can lead to an out-of-bounds read in TIFFCleanup, an invalid free in TIFFClose or t2p_free, memory corruption in t2p_readwrite_pdf_image, or a double free in t2p_free. Given these possibilities, it probably could cause arbitrary code execution.
