A flaw was found in httpd. When deployed on Windows environments, an out-of-bounds write vulnerability occurs while processing path requests containing short 8.3 file names that expand beyond allocated memory buffers. A remote attacker can exploit this flaw by sending crafted HTTP requests, potentially leading to memory corruption, a Denial of Service (DoS) via server crash, or arbitrary code execution.
