CVE-2026-34535: 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 segmentation fault (SEGV) in CIccTagArray::Cleanup(). The issue is observable under UBSan/ASan as misaligned member access / misaligned pointer loads followed by an invalid read leading to process crash when running iccRoundTrip on a malicious profile. This issue has been patched in version 2.3.1.6.
AI Analysis
Technical Summary
The iccDEV library, used for handling ICC color management profiles, contains a heap-based buffer overflow vulnerability in versions before 2.3.1.6. Specifically, a crafted ICC profile can cause misaligned member access and invalid reads during the cleanup of tag arrays, triggering a segmentation fault. This vulnerability is detectable with sanitizers such as UBSan and ASan. The vulnerability is tracked as CVE-2026-34535 with a CVSS 3.1 base score of 6.2 (medium severity), reflecting a local attack vector with no required privileges or user interaction, and impacts availability by causing a crash. The issue has been fixed in iccDEV version 2.3.1.6.
Potential Impact
Exploitation of this vulnerability results in a denial of service via application crash due to heap-based buffer overflow and invalid memory access. There is no indication of confidentiality or integrity impact. The attack requires local access to supply a crafted ICC profile to the vulnerable iccDEV library. No known exploits in the wild have been reported.
Mitigation Recommendations
Upgrade to iccDEV version 2.3.1.6 or later, where this vulnerability has been patched. No other mitigation is indicated or required according to the available data.
