CVE-2026-34537 MEDIUM This Month

Local denial of service in iccDEV prior to version 2.3.1.6 allows unauthenticated local attackers to crash applications processing ICC color profiles by crafting malicious profiles that trigger undefined behavior through invalid enum values in CIccOpDefEnvVar::Exec(). The vulnerability requires local file access but no privilege escalation, with an EPSS score of 6.2 reflecting moderate real-world risk. No public exploit code or active exploitation has been identified at the time of analysis.

CVE-2026-34533 MEDIUM This Month

Undefined Behavior in iccDEV prior to version 2.3.1.6 allows local attackers to cause a denial of service by supplying a crafted ICC color profile containing invalid enum values for icChannelFuncSignature, which triggers an application crash during profile processing in CIccCalculatorFunc::ApplySequence(). The vulnerability requires local file access or the ability to provide a malicious ICC profile to an application using the library; no public exploit code has been identified.

CVE-2026-34549 MEDIUM This Month

Denial of service via crafted ICC color profile in iccDEV library prior to version 2.3.1.6 triggers undefined behavior through invalid left shift operations on 32-bit unsigned integers, causing application crashes. The vulnerability affects all iccDEV versions before 2.3.1.6 and requires only local file access to exploit (no authentication or user interaction required beyond opening a malicious profile). No public exploit code or active exploitation has been identified at time of analysis.

CVE-2026-34547 MEDIUM This Month

Denial of service via undefined behavior in iccDEV versions prior to 2.3.1.6 allows local attackers to crash the iccDumpProfile tool by supplying a crafted ICC color profile. The vulnerability exploits an unsafe memory operation in IccUtil.cpp triggered during profile parsing, resulting in application termination with no authentication required. No public exploit code or active exploitation has been reported at time of analysis.

An undefined behavior vulnerability exists in the Firefox Audio/Video component that could lead to information disclosure. This affects all Firefox versions prior to 149. While specific exploitation details are limited due to missing CVSS and CWE data, the vulnerability's classification as information disclosure suggests an attacker could potentially access sensitive audio or video processing data or bypass security boundaries within the multimedia subsystem.

CVE-2025-54811 HIGH This Week

OpenPLC_V3 has a vulnerability in the enipThread function that occurs due to the lack of a return value. This leads to a crash when the server loop ends and execution hits an illegal ud2 instruction. This issue can be triggered remotely without authentication by starting the same server multiple times or if the server exits unexpectedly. The vulnerability allows an attacker to cause a Denial of Service (DoS) against the PLC runtime, stopping any PC started remotely without authentication. This results in the PLC process crashing and halting all automation or control logic managed by OpenPLC.
