CVE-2010-2738 is a vulnerability that was discovered in the Microsoft Windows kernel-mode drivers. The vulnerability existed due to a flaw in the way Windows kernel-mode drivers handle specially crafted TrueType fonts. An attacker could exploit this vulnerability by convincing a user to view or open a maliciously crafted font file, which would then allow the attacker to execute arbitrary code on the affected system with elevated privileges.
This vulnerability was first discovered and reported in 2010, and a patch was released by Microsoft shortly thereafter that addressed the issue. However, it's important to note that this vulnerability could still pose a threat to systems that have not been updated with the latest security patches.
If left unpatched, this vulnerability could allow attackers to gain complete control of an affected system, potentially resulting in data theft, system damage or disruption of critical services. As with any vulnerability, it's important for users and organizations to promptly apply available security updates and exercise caution when opening files from unknown sources.
