CVE-2026-34534
Prior to version 2.3.1.6, a crafted ICC profile can trigger a heap-buffer-overflow (HBO) in CIccMpeSpectralMatrix::Describe().
Does this matter?
Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.
Description
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger a heap-buffer-overflow (HBO) in CIccMpeSpectralMatrix::Describe(). The issue is observable under AddressSanitizer as an out-of-bounds heap read when running iccDumpProfile on a malicious profile. This issue has been patched in version 2.3.1.6.
