CVE-2026-62343: ImageMagick: Heap Buffer Over-Write in morphology operation when an invalid kernel is provided

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: 0.09% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: imagemagick (Debian:12) 8:6.9.11.60+dfsg-1.6+deb12u14; imagemagick (Debian:13) 8:7.1.1.43+dfsg1-1+deb13u13; imagemagick (Debian:14) 8:7.1.2.26+dfsg1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to imagemagick (Debian:12) 8:6.9.11.60+dfsg-1.6+deb12u14; imagemagick (Debian:13) 8:7.1.1.43+dfsg1-1+deb13u13; imagemagick (Debian:14) 8:7.1.2.26+dfsg1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 6.9.13-51 and 7.0.1-0 and above prior to 7.1.2-26, an invalid kernel can cause a heap buffer over-write when performing a morphology operation with a user supplied kernel. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26.
