DescriptionNVD

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.

AnalysisAI

Heap buffer overflow in iccDEV prior to version 2.3.1.6 allows local attackers to trigger a denial of service via a malicious ICC color profile, causing out-of-bounds heap reads in the CIccMpeSpectralMatrix::Describe() function when processing profiles with iccDumpProfile. The vulnerability requires local file access but no user interaction or authentication, with confirmed patch availability in version 2.3.1.6.
