Detailsinfo A vulnerability was found in InternationalColorConsortium iccDEV and classified as critical. Affected by this issue is the function icMemDump in the library IccProfLib/IccUtil.cpp of the component ICC Color Profile Handler. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is availability. CVE summarizes: 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. The advisory is available at github.com. This vulnerability is handled as CVE-2026-34540 since 03/30/2026. The exploitation is known to be easy.
