CVE-2026-24403: iccDEV Undefined Behavior in CIccProfile::CheckHeader() Leads to Integer Overflow

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.47% (FIRST EPSS).
  • 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: InternationalColorConsortium iccDEV 2.3.1.2.

Low priority for now. Upgrade to InternationalColorConsortium iccDEV 2.3.1.2 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

iccDEV provides libraries and tools for interacting with, manipulating, and applying ICC color management profiles. In versions 2.3.1.1 and below, an integer overflow vulnerability exists in icValidateStatus CIccProfile::CheckHeader() when user-controllable input is incorporated into profile data unsafely. Tampering with tag tables, offsets, or size fields can trigger parsing errors, memory corruption, or DoS, potentially enabling arbitrary Code Execution or bypassing application logic. This issue has been fixed in version 2.3.1.2.
