Subject: [PATCH] dnsproxy: Address CVE-2025-32366 vulnerability
In Connman 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)). Here, rdlen may be larger
than the amount of remaining packet data in the current state of
parsing. As a result, values of stack memory locations may be sent
over the network in a response.
This patch adds a check to ensure that (*end + *rdlen) does not exceed
the valid range. If the condition is violated, the function returns
-EINVAL.
CVE: CVE-2025-32366

Subject: [PATCH] dnsproxy: Fix NULL/empty lookup causing potential crash
In ConnMan through 1.44, the lookup string in ns_resolv in dnsproxy.c
can be NULL or an empty string when the TC (Truncated) bit is set in
a DNS response. This allows attackers to cause a denial of service
(application crash) or possibly execute arbitrary code, because those
lookup values lead to incorrect length calculations and incorrect
memcpy operations.
This patch includes a check to make sure loookup value is valid before
using it. This helps avoid unexpected value when the input is empty or
incorrect.
