Listen to this Post
CVE-2026-30987 is a stack-based buffer overflow vulnerability in iccDEV, a library for handling ICC color profiles, affecting versions prior to 2.3.1.5. The flaw exists in the `CIccTagNum<>::GetValues()` function, which processes tag data from ICC profiles. Due to insufficient bounds checking, when a malformed ICC profile with oversized tag values is parsed, the function writes beyond the allocated stack buffer. This corruption overwrites adjacent memory, including return addresses and local variables. An attacker can craft a malicious ICC profile and induce a user or application to process it, leading to arbitrary code execution or application crash. The overflow is triggered during tag value retrieval, where input size validation is missing. The issue is fixed in version 2.3.1.5 by adding proper boundary checks. The vulnerability was publicly disclosed on March 10, 2026, with a critical severity due to its potential for remote code execution in user-assisted scenarios. All users should upgrade immediately to mitigate risks.
DailyCVE Form:

How Exploit:
An attacker crafts an ICC profile with an oversized tag value targeting the `CIccTagNum<>::GetValues()` function. When processed, the overflow overwrites the stack return address, redirecting execution to attacker-supplied shellcode. Exploit development requires bypassing stack canaries and ASLR, but due to the lack of bounds checking, memory corruption is guaranteed. Public proof-of-concept code may emerge, leveraging user-assisted vectors like opening malicious images in vulnerable applications.
Protection from this CVE:
Upgrade to iccDEV version 2.3.1.5 immediately. If patching is delayed, avoid processing ICC profiles from untrusted sources. Recompile applications with stack protection (-fstack-protector-strong) and non-executable stack flags. Use security tools to monitor for abnormal crashes. Apply vendor patches as soon as they are available.
Impact:
Arbitrary code execution within the context of the application using iccDEV, leading to system compromise, data exfiltration, or denial of service. Applications relying on ICC color management (e.g., image editors, PDF viewers, printers) are vulnerable. The critical severity stems from the ease of triggering the overflow via malicious files and the potential for full system takeover.
