Noroxi assessment

Priority: Monitor (action score 18/100)

  • 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: 2.7% (FIRST EPSS); higher than 86.5% of all records.
  • Fixed version: imagemagick (Debian:12) 8:6.7.7.10-3; imagemagick (Debian:6.0) 8:6.6.0.4-3+squeeze6.

Low priority for now. Upgrade to imagemagick (Debian:12) 8:6.7.7.10-3; imagemagick (Debian:6.0) 8:6.6.0.4-3+squeeze6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The Magick_png_malloc function in coders/png.c in ImageMagick 6.7.8 and earlier does not use the proper variable type for the allocation size, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG file that triggers incorrect memory allocation.
