Heap Overflow Buffer Overflow

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.

Analysis

Heap buffer overflow in iccDEV prior to version 2.3.1.6 allows denial of service via a crafted ICC color profile that triggers out-of-bounds heap read in icMemDump() when iccDumpProfile processes malformed tag contents. The vulnerability affects local attackers without authentication or user interaction, though the practical attack surface depends on how iccDumpProfile is invoked in consuming applications. …
