CVE-2026-34539: 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 and TIFF input can trigger a heap-buffer-overflow (HBO) in CTiffImg::WriteLine(). The issue is observable under AddressSanitizer as an out-of-bounds heap read when running iccSpecSepToTiff on a malicious .icc + .tif pair, leading to a crash during TIFF strip writing. 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, when the iccSpecSepToTiff tool processes a maliciously crafted .icc and .tif file pair, the CTiffImg::WriteLine() function performs an out-of-bounds heap read, observable under AddressSanitizer, leading to a crash during TIFF strip writing. This vulnerability has been patched in version 2.3.1.6.
Potential Impact
The vulnerability results in a denial of service (application crash) due to heap-buffer-overflow when processing specially crafted ICC and TIFF files. There is no indication of confidentiality or integrity impact. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade iccDEV to version 2.3.1.6 or later, where this heap-based buffer overflow vulnerability has been fixed. No other mitigation is required as the issue is resolved by the official patch.
