In commit 770f915497, libjwt was bumped
from 1.17.2 to 3.2.0, which is a big bump. And the libjwt website
states "Version 3 of LibJWT is a complete overhaul of the code. Please
see documentation for usage."
And indeed, this version bump breaks the build of Asterisk:
res_stir_shaken/attestation.c: In function 'pack_payload':
res_stir_shaken/attestation.c:357:9: error: implicit declaration of function 'jwt_add_grants_json' [-Wimplicit-function-declaration]
357 | jwt_add_grants_json(jwt, payload_str);

In file included from /home/autobuild/autobuild/instance-11/output-1/build/asterisk-22.3.0/include/asterisk/module.h:39,

367 | RAII_VAR(jwt_t *, jwt, NULL, jwt_free);
| ^~~~~~~~
To fix this, let's use the bundled version of libjwt in Asterisk,
since even Asterisk master hasn't been fixed to be compatible with
libjwt 3.x.
Of course, this raises the question of whether the separate libjwt
package should be removed, as it is anyway only used by Asterisk.

20.8.1 contains a fix for CVE-2024-35190. However, the vulnerability
was introduced in commit 68a49128253f677f9e1b235c70d2316342372f7d
between 20.7.0 and 20.8.0, and Buildroot was using 20.7.0, so we were
not affected by this vulnerability.
Patch 0005 is applied upstream.

We unconditionally configure asterisk with --with-crypt, so the build
currently fails under glibc since it removed crypt in 2.39, and we
explicitly remove it from external toolchains as well, whatever the
version, causing build failures such as:
checking for mandatory modules: OPENSSL BKTR CRYPT ILBC JANSSON LIBEDIT LIBJWT LIBXML2 PJPROJECT SQLITE3 ZLIB... fail
configure: ***
configure: *** The CRYPT installation appears to be missing or broken.
configure: *** Either correct the installation, or run configure
configure: *** including --without-crypt.
Fixing this could be done in two ways: either make libxcrypt a mandatory
dependency under glibc, and continue unconditionally enabling crypt
support, or only enable crypt support when libxcrypt is available or
this was a non-glibc toolchain.
We chose the first option, to keep the existing behaviour (crypt support
is always enabled), to be aligned with other packages (libxcrypt is
selected under glibc toolchains), and because it is also the simplest.

Fixes the following security issues:
16.24.1:
CVE-2021-37706 / AST-2022-004: pjproject: integer underflow on STUN message
The header length on incoming STUN messages that contain an ERROR-CODE
attribute is not properly checked. This can result in an integer underflow.
Note, this requires ICE or WebRTC support to be in use with a malicious
remote party.
https://seclists.org/fulldisclosure/2022/Mar/0
CVE-2022-23608 / AST-2022-005: pjproject: undefined behavior after freeing a
dialog set
When acting as a UAC, and when placing an outgoing call to a target that then
forks Asterisk may experience undefined behavior (crashes, hangs, etc…)
after a dialog set is prematurely freed.
https://seclists.org/fulldisclosure/2022/Mar/1
CVE-2022-21723 / AST-2022-006: pjproject: unconstrained malformed multipart
SIP message
If an incoming SIP message contains a malformed multi-part body an out of
bounds read access may occur, which can result in undefined behavior. Note,
it’s currently uncertain if there is any externally exploitable vector
within Asterisk for this issue, but providing this as a security issue out
of caution.

16.25.2:
CVE-2022-26498 / AST-2022-001: res_stir_shaken: resource exhaustion with
large files
When using STIR/SHAKEN, it’s possible to download files that are not
certificates. These files could be much larger than what you would expect to
download.
https://seclists.org/fulldisclosure/2022/Apr/17
CVE-2022-26499 / AST-2022-002: res_stir_shaken: SSRF vulnerability with
Identity header
When using STIR/SHAKEN, it’s possible to send arbitrary requests like GET to
interfaces such as localhost using the Identity header.

CVE-2022-26651 / AST-2022-003: func_odbc: Possible SQL Injection

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.
https://downloads.asterisk.org/pub/security/AST-2020-003.pdf
- 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.
https://downloads.asterisk.org/pub/security/AST-2020-004.pdf
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.
https://downloads.asterisk.org/pub/security/AST-2021-001.pdf
- 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.
https://downloads.asterisk.org/pub/security/AST-2021-002.pdf
- 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.
https://downloads.asterisk.org/pub/security/AST-2021-004.pdf
- 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.
https://downloads.asterisk.org/pub/security/AST-2021-005.pdf
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.
https://downloads.asterisk.org/pub/security/AST-2021-006.pdf
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:

Fixes the following security issues:
- AST-2020-001: Remote crash in res_pjsip_session
Upon receiving a new SIP Invite, Asterisk did not return the created
dialog locked or referenced.
- AST-2020-002: Outbound INVITE loop on challenge with different nonce
If Asterisk is challenged on an outbound INVITE and the nonce is changed
in each response, Asterisk will continually send INVITEs in a loop. This
causes Asterisk to consume more and more memory since the transaction will
never terminate (even if the call is hung up), ultimately leading to a
restart or shutdown of Asterisk. Outbound authentication must be
configured on the endpoint for this to occur.

A SIP request can be sent to Asterisk that can change a SIP peer’s IP
address. A REGISTER does not need to occur, and calls can be hijacked as a
result. The only thing that needs to be known is the peer’s name;
authentication details such as passwords do not need to be known. This
vulnerability is only exploitable when the “nat” option is set to the
default, or “auto_force_rport”.
