Microsoft has issued a warning about a critical vulnerability in Canon printer drivers. The flaw was discovered by researchers at Microsoft’s Offensive Research and Security Engineering team and is identified as CVE-2025-1268 with a CVSS score of 9.4. This vulnerability affects various Canon printer drivers, including those for production printers, office/small office multifunction printers, and laser printers.
The specific issue is an out-of-bounds vulnerability in the EMF recode processing of printer drivers such as Generic Plus PCL6, UFR II, LIPS4, LIPSXL, and PS. Exploiting this flaw could allow an attacker to disrupt printing operations or potentially execute arbitrary code under specific circumstances.
Canon swiftly responded to the discovery and plans to release updated printer drivers on its local sales websites. The company also addressed additional vulnerabilities that could lead to remote code execution or denial-of-service attacks on its printers. Canon’s advisory highlighted the risk of buffer overflow vulnerabilities in certain models of Canon Laser Printers and Small Office Multifunctional Printers.
When these products are directly connected to the internet without a router, they are susceptible to potential exploitation by third parties to execute arbitrary code or launch DoS attacks. Canon urges customers to update to the latest printer driver versions to mitigate these risks.
The news of this critical flaw in Canon printer drivers underscores the ongoing challenges in ensuring the security of connected devices. With the proliferation of Internet of Things (IoT) devices in homes and offices, the need for robust cybersecurity measures is more critical than ever. Vulnerabilities in essential devices like printers can expose organizations and individuals to significant risks of cyberattacks.
Experts emphasize the importance of regular software updates and patches to address known vulnerabilities promptly. The collaboration between technology companies like Microsoft and Canon in identifying and addressing security flaws is crucial in safeguarding users from potential threats.
In the evolving landscape of cybersecurity threats, businesses and individuals must remain vigilant and proactive in securing their digital assets. The rapid pace of technological advancements demands a corresponding focus on cybersecurity measures to mitigate risks effectively.
As cyber threats continue to evolve, it is essential for organizations to stay informed about potential vulnerabilities in their systems and take proactive steps to enhance their cybersecurity posture. The recent warning from Microsoft serves as a reminder of the constant vigilance required to protect against emerging cyber risks.
By leveraging insights from security researchers and industry experts, organizations can strengthen their defenses and minimize the impact of potential security incidents. The collaborative efforts of companies like Microsoft and Canon in addressing vulnerabilities demonstrate a shared commitment to enhancing cybersecurity resilience across the digital ecosystem.
