"According to the version of the libtiff package installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerability :
- 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.(CVE-2017-9935)
