Fixes the following security issues:
16.15.0:
- ASTERISK-29057: pjsip: Crash on call rejection during high load
16.15.1:
- AST-2020-003: Remote crash in res_pjsip_diversion
A crash can occur in Asterisk when a SIP message is received that has a
History-Info header, which contains a tel-uri.

- AST-2020-004: Remote crash in res_pjsip_diversion
A crash can occur in Asterisk when a SIP 181 response is received that has
a Diversion header, which contains a tel-uri.

16.16.0:
- ASTERISK-29219: res_pjsip_diversion: Crash if Tel URI contains History-Info
16.16.1:
- AST-2021-001: Remote crash in res_pjsip_diversion
If a registered user is tricked into dialing a malicious number that sends
lots of 181 responses to Asterisk, each one will cause a 181 to be sent
back to the original caller with an increasing number of entries in the
“Supported” header. Eventually the number of entries in the header
exceeds the size of the entry array and causes a crash.

- AST-2021-002: Remote crash possible when negotiating T.38
When re-negotiating for T.38 if the initial remote response was delayed
just enough Asterisk would send both audio and T.38 in the SDP. If this
happened, and the remote responded with a declined T.38 stream then
Asterisk would crash.

- AST-2021-003: Remote attacker could prematurely tear down SRTP calls
An unauthenticated remote attacker could replay SRTP packets which could
cause an Asterisk instance configured without strict RTP validation to
tear down calls prematurely.
https://downloads.asterisk.org/pub/security/AST-2021-003.pdf
- AST-2021-004: An unsuspecting user could crash Asterisk with multiple
hold/unhold requests
Due to a signedness comparison mismatch, an authenticated WebRTC client
could cause a stack overflow and Asterisk crash by sending multiple
hold/unhold requests in quick succession.

- AST-2021-005: Remote Crash Vulnerability in PJSIP channel driver
Given a scenario where an outgoing call is placed from Asterisk to a
remote SIP server it is possible for a crash to occur.

16.16.2:
- AST-2021-006: Crash when negotiating T.38 with a zero port
When Asterisk sends a re-invite initiating T.38 faxing and the endpoint
responds with a m=image line and zero port, a crash will occur in
Asterisk.
This is a reoccurrence of AST-2019-004.

16.17.0:
- ASTERISK-29203 / AST-2021-002 — Another scenario is causing a crash
- ASTERISK-29260: sRTP Replay Protection ignored; even tears down long calls
- ASTERISK-29227: res_pjsip_diversion: sending multiple 181 responses causes
memory corruption and crash
16.19.1:
- AST-2021-007: Remote Crash Vulnerability in PJSIP channel driver
When Asterisk receives a re-INVITE without SDP after having sent a BYE
request a crash will occur. This occurs due to the Asterisk channel no
longer being present while code assumes it is.
https://downloads.asterisk.org/pub/security/AST-2021-007.pdf
- AST-2021-008: Remote crash when using IAX2 channel driver
If the IAX2 channel driver receives a packet that contains an unsupported
media format it can cause a crash to occur in Asterisk.
https://downloads.asterisk.org/pub/security/AST-2021-008.pdf
- AST-2021-009: pjproject/pjsip: crash when SSL socket destroyed during
handshake
Depending on the timing, it’s possible for Asterisk to crash when using a
TLS connection if the underlying socket parent/listener gets destroyed
during the handshake.
https://downloads.asterisk.org/pub/security/AST-2021-009.pdf
16.20.0:
- ASTERISK-29415: Crash in PJSIP TLS transport
- ASTERISK-29381: chan_pjsip: Remote denial of service by an authenticated
user
In addition, a large number of bugfixes.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
