CVE-2026-34534: CWE-122: Heap-based Buffer Overflow in InternationalColorConsortium iccDEV
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.
AI Analysis
Technical Summary
The InternationalColorConsortium's iccDEV library, used for handling ICC color management profiles, contains a heap-based buffer overflow vulnerability (CWE-122) in the CIccMpeSpectralMatrix::Describe() function. Specifically, when processing a maliciously crafted ICC profile, an out-of-bounds heap read occurs, observable under AddressSanitizer during execution of iccDumpProfile. This vulnerability affects all versions before 2.3.1.6 and has been fixed in that version.
Potential Impact
The vulnerability can cause a heap-based buffer overflow leading to a potential denial of service (application crash) due to out-of-bounds heap reads. According to the CVSS vector, it requires local access (AV:L) with low attack complexity and no privileges or user interaction. There is no indication of confidentiality or integrity impact, only availability is affected. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade iccDEV to version 2.3.1.6 or later, where this heap-based buffer overflow vulnerability has been patched. No other mitigation steps are indicated or necessary according to the available data.
