Unchecked `atoi()` on declared payload size let a client
request up to `INT_MAX`, forcing the server to write ~20 GB
per request via the download phase. Short `#` frames also
triggered OOB reads on `s[1..3]`.
- Gate `#` branch on `JPFLAG_AUTHED`.
- Cap declared size at 10 MiB (`VERTO_SPEED_TEST_MAX_SIZE`).
- Replace `atoi()` with bounded `strtol()`.
- Require `bytes >= 4` before indexing `s[1..3]`.
Cap `Content-Length` at `HTTP_POST_MAX_BODY` (10 MiB) and size the
allocation to the actual body length (`content_length + 1` for
the trailing NUL).
Also fix `WS_BLOCK` units — `kws_raw_read` takes ms, set to 10000.
ffmpeg@5 changed to ffmpeg@7
Note: tested ffmpeg@8 but it causes missing ft2build.h in truetype include library.
libpq@16 changed to libpq@18

Route IPv6 writes in `switch_stun_packet_attribute_add_binded_address`
and `switch_stun_packet_attribute_add_xor_binded_address` through
`switch_stun_ipv6_t` (16-byte `address[]`) instead of `switch_stun_ip_t`
(4-byte `uint32_t address`).
Add IPv4/IPv6 unit tests for both encoders.

Implement SIP 603+ (ATIS-1000099) support for FCC analytics-based call blocking compliance.
Detection:
- Detect incoming 603+ responses by checking "Network Blocked" phrase
and "v=analytics1;" in the `Reason` header text
- Set `sip_603plus_reason` channel variable on both legs for CDR visibility
Passthrough control:
- `sip_603plus_passthrough=true`: forward 603+ phrase and Reason header
- `sip_603plus_passthrough=false`: strip `Reason` header, send clean `603 Decline`
- Not set: existing behavior preserved
- Works independently of `disable_q850_reason` for selective forwarding
`sofia_process_dispatch_event_in_thread` allocated `td` from a memory pool,
then `sofia_msg_thread_run_once` destroyed that same pool after processing
the event — leaving `td` dangling when the thread pool worker accessed it.
Allocate `td` with `switch_zmalloc` (`td->alloc = 1`) so the worker frees it
safely after the function returns. Remove the now-unused `pool` field from
`sofia_dispatch_event_t`.
`switch_core_session_thread_pool_launch()` allocated the thread data (`td`)
from the session pool. However, `switch_core_session_thread()` destroys
the session pool before returning, leaving td as a dangling pointer.
The worker then accesses `td->running` and `td->pool` — a use-after-free
that crashes under memory pressure when the freed pool is reused.
Allocate `td` with `switch_zmalloc()` and set `td->alloc = 1` so the worker frees it
after the task completes. This ensures `td` outlives the session pool
destruction.
Changes:
- Snapshot `erl_errno` after `ei_xreceive_msg_tmo()` — outbound `ei_*` calls in the same loop iteration clobber the thread-local errno before the listener checks it, causing wrong exit decisions and misleading logs.
- Fix `switch_size_t ` cast of `int` in `ei_link`* — `(switch_size_t *)&index` reads/writes 8 bytes through a 4-byte `int` on LP64. Use a real `switch_size_t` local.
- Dispatch `ERL_NEWER_REFERENCE_EXT` — newer OTP encodes refs with this tag; spawn replies from modern nodes were silently dropped to the default branch.
- Handle `ERL_EXIT2` — processes killed via `erlang:exit/2` arrive with this tag, not `ERL_EXIT`. Without it, sessions stayed attached to dead Erlang pids.
- Modernize `-spec` syntax in `freeswitch.erl` — old `-spec(F/N :: (...))` form was removed in OTP 21+; module no longer compiled.
- Fix multiple memory issues:
- `ei_hash_ref()`: replace unbounded `sprintf` with `snprintf` + shared `EI_HASH_REF_LEN`.
- `handle_msg_sendevent` / `handle_msg_sendmsg`: free the heap `value` on `ei_decode_string` failure; remove dead `if (!fail)` branches.
- `listener_main_loop`: free `buf`/`rbuf` on the two `handle_msg` early-exit paths.
- `erlang_sendmsg_function` app: move `ei_x_new_with_version` past arg validation and add `ei_x_free` at the end.
