CVE-2026-34540 Details
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 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.
A heap-buffer-overflow vulnerability has been identified in iccDEV versions prior to 2.3.1.6. This issue arises when a crafted ICC profile is processed by the 'iccDumpProfile' tool, specifically in the 'icMemDump()' function. The vulnerability occurs as the function attempts to dump and describe malformed tag contents, leading to an out-of-bounds heap read. This vulnerability is related to improper handling of tag data sizes, allowing for memory access violations that could potentially be exploited.
Users can update to iccDEV version 2.3.1.6 or later, where this vulnerability has been fixed.
