NewCVE-2025-32366 (opens in a new tab)How to fix?
There is no fixed version for Debian:13 connman.
NVD Description
Note: Versions mentioned in the description apply only to the upstream connman package and not the connman package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
In ConnMan through 1.44, parse_rr in dnsproxy.c has a memcpy length that depends on an RR RDLENGTH value, i.e., *rdlen=ntohs(rr->rdlen) and memcpy(response+offset,*end,*rdlen) without a check for whether the sum of *end and *rdlen exceeds max. Consequently, *rdlen may be larger than the amount of remaining packet data in the current state of parsing. Values of stack memory locations may be sent over the network in a response.
