CyberRota Analysis
AI-GeneratedThe vulnerability in the tftp-hpa daemon allows remote, unauthenticated attackers to exploit improperly handled inverse remap rules, leading to out-of-bounds read/write operations. This can result in a denial of service, causing the daemon to crash when a specially crafted request is sent. Organizations using tftp-hpa should prioritize patching this flaw to mitigate the risk of service disruptions.

Original NVD Description
A flaw was found in tftp-hpa. When the `in.tftpd` remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the `genmatchstring()` function. This leads to out-of-bounds read/write operations. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted request, causing the daemon to crash and resulting in a denial of service.
