Advisory overview
TFTP which is the abbreviation of Trivial File Fransfer Protocol enables users to transfer files between local host and remote machine. This package tftp is a client implementing TFTP. Security Fix(es): 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.(CVE-2026-85234)
