CVE-2026-34549: CWE-758: Reliance on Undefined, Unspecified, or Implementation-Defined Behavior 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, there is an Undefined Behavior (UB) condition in IccUtil.cpp triggered by a crafted input profile. Under UndefinedBehaviorSanitizer, the issue is reported as invalid left shift operations on icUInt32Number (unsigned 32-bit) where the shifted value “cannot be represented” in that type. This issue has been patched in version 2.3.1.6.
AI Analysis
Technical Summary
The InternationalColorConsortium's iccDEV library versions before 2.3.1.6 contain a vulnerability classified as CWE-758 (Reliance on Undefined, Unspecified, or Implementation-Defined Behavior). Specifically, in IccUtil.cpp, a crafted input profile can trigger invalid left shift operations on an unsigned 32-bit integer, which is reported by UndefinedBehaviorSanitizer as an operation where the shifted value cannot be represented in the type. This undefined behavior can cause application instability or crashes. The issue is fixed in version 2.3.1.6.
Potential Impact
The vulnerability does not affect confidentiality or integrity but impacts availability by potentially causing application crashes or denial of service when processing maliciously crafted ICC profiles. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade iccDEV to version 2.3.1.6 or later, where this undefined behavior issue has been patched. No other mitigations are specified.
