CVE-2026-34540: 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 icMemDump() when iccDumpProfile attempts to dump/describe malformed tag contents. The issue is observable under AddressSanitizer as an out-of-bounds heap read in icMemDump(...) at IccProfLib/IccUtil.cpp:1002, reachable via CIccTagUnknown::Describe(). 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 versions before 2.3.1.6. Specifically, a crafted ICC profile with malformed tag contents can trigger an out-of-bounds heap read in the icMemDump() function, as observed under AddressSanitizer at IccProfLib/IccUtil.cpp line 1002. This occurs during the execution of CIccTagUnknown::Describe() when iccDumpProfile attempts to dump or describe the profile data. The issue has been patched in version 2.3.1.6.
Potential Impact
The vulnerability can cause a heap-based buffer overflow leading to a denial of service (application crash) due to out-of-bounds heap reads. According to the CVSS vector, it requires local access (AV:L), has low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts availability (A:H) without affecting confidentiality or integrity. There are no known exploits in the wild at this time.
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 is indicated or required.
