libvips unpremultiply.c vips_unpremultiply_build out-of-bounds

Noroxi assessment

Priority: Monitor (action score 7/100)

  • 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: 0.20% (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: vips (Debian:12) 8.14.1-3+deb12u3; vips (Debian:13) 8.16.1-1+deb13u1; vips (Debian:14) 8.18.0-3.
  • Severity is disputed: the assigning authority (CNA) scores it 4.8, NVD 1.9.

Low priority for now. Upgrade to vips (Debian:12) 8.14.1-3+deb12u3; vips (Debian:13) 8.16.1-1+deb13u1; vips (Debian:14) 8.18.0-3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw has been found in libvips 8.19.0. This vulnerability affects the function vips_unpremultiply_build of the file libvips/conversion/unpremultiply.c. Executing a manipulation of the argument alpha_band can lead to out-of-bounds read. The attack needs to be launched locally. The exploit has been published and may be used. This patch is called 7215ead1e0cd7d3703cc4f5fca06d7d0f4c22b91. A patch should be applied to remediate this issue.
