Stack-based Buffer Overflow in Unreal Engine's Logging Function

CVE-2007-4442

What is CVE-2007-4442?

A stack-based buffer overflow vulnerability exists in the logging function of Unreal Engine, affecting versions 2003 and 2004. This security issue arises from the internal web server's handling of long .gif filenames in the images/ directory. An attacker can exploit this vulnerability by sending a specially crafted request that causes a denial of service, leading to an application crash. The flaw is related to the conversion process from Unicode to ASCII, which is inadequate for handling excessively long input. Remediation steps should be taken to mitigate the risk posed by potential exploitation.
