CVE-2026-35591· NVD / CVE Program· CNA GitHub_M

Possible heap-based buffer overflow when decoding TIFF image containing well-crafted tile

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: libvips libvips 8.18.2.

Low priority for now. Upgrade to libvips libvips 8.18.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

libvips is a fast image processing library with low memory needs. The `tiffload` operation in libvips versions before and including 8.18.1 could incorrectly determine the number of channels in a JPEG or JPEG2000-encoded tile within a TIFF image, leading to a possible buffer overflow. This has been patched in version 8.18.2.
