📋 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.
