CVE-2021-32686

A race condition between callback and destroy, due to the accepted socket having no group lock. Second, the SSL socket parent/listener may get destroyed during handshake. s. They cause crash, resulting in a denial of service.

CVE-2021-37706

An incoming STUN message contains an ERROR-CODE attribute, the header length is not checked before performing a subtraction operation, potentially resulting in an integer underflow scenario. This issue affects all users that use STUN. A malicious actor located within the victim's network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victim's machine

CVE-2021-41141

In various parts of PJSIP, when error/failure occurs, it is found that the function returns without releasing the currently held locks. This could result in a system deadlock, which cause a denial of service for the users.

CVE-2021-43299

Stack overflow in PJSUA API when calling pjsua_player_create. An attacker-controlled filename argument may cause a buffer overflow since it is copied to a fixed-size stack buffer without any size validation.

CVE-2021-43300

Stack overflow in PJSUA API when calling pjsua_recorder_create. An attacker-controlled filename argument may cause a buffer overflow since it is copied to a fixed-size stack buffer without any size validation.

CVE-2021-43301

Stack overflow in PJSUA API when calling pjsua_playlist_create. An attacker-controlled file_names argument may cause a buffer overflow since it is copied to a fixed-size stack buffer without any size validation.

CVE-2021-43302

Read out-of-bounds in PJSUA API when calling pjsua_recorder_create. An attacker-controlled filename argument may cause an out-of-bounds read when the filename is shorter than 4 characters.

CVE-2021-43303

Buffer overflow in PJSUA API when calling pjsua_call_dump. An attacker-controlled buffer argument may cause a buffer overflow, since supplying an output buffer smaller than 128 characters may overflow the output buffer, regardless of the maxlen argument supplied

CVE-2021-43804

An incoming RTCP BYE message contains a reason's length, this declared length is not checked against the actual received packet size, potentially resulting in an out-of-bound read access. A malicious actor can send a RTCP BYE message with an invalid reason length

CVE-2021-43845

if incoming RTCP XR message contain block, the data field is not checked against the received packet size, potentially resulting in an out-of-bound read access

CVE-2022-21722

it is possible that certain incoming RTP/RTCP packets can potentially cause out-of-bound read access. This issue affects all users that use PJMEDIA and accept incoming RTP/RTCP.

CVE-2022-21723

Parsing an incoming SIP message that contains a malformed ... [Please see the references for more information on the vulnerabilities]");
