CVE-2017-9935: In LibTIFF 4.0.8, there is a heap-based buffer overflow in the t2p_write_pdf function in tools/tiff2pdf.c.

HighCVSS 8.8 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 3.9% (FIRST EPSS); higher than 90.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: tiff (Alpine:v3.10) 4.0.9-r6; tiff (Alpine:v3.5) 4.0.9-r5; tiff (Debian:12) 4.0.9-2.

Low priority for now. Upgrade to tiff (Alpine:v3.10) 4.0.9-r6; tiff (Alpine:v3.5) 4.0.9-r5; tiff (Debian:12) 4.0.9-2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
