PJSIP is a free and open source multimedia communication library written in C. A buffer overflow vulnerability in versions 2.13 and prior affects applications that use PJSIP DNS resolver. It doesn't affect PJSIP users who do not utilise PJSIP DNS resolver. This vulnerability is related to CVE-2022-24793. The difference is that this issue is in parsing the query record `parse_query()`, while the issue in CVE-2022-24793 is in `parse_rr()`. A patch is available as commit `d1c5e4d` in the `master` branch. A workaround is to disable DNS resolution in PJSIP config (by setting `nameserver_count` to zero) or use an external resolver implementation instead.

The remote Debian 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5956 advisory.

    Multiple vulnerabilities were found to affect ring, a secure and     distributed voice, video, and chat platform.

    CVE-2021-32686

        The embedded copy of pjproject is affected by this CVE.
        A race condition between callback and destroy, due to the accepted socket         having no group lock. Additionally, the SSL socket parent/listener may get         destroyed during handshake. Both issues were reported to happen         intermittently in heavy load TLS connections. They cause a crash, resulting         in a denial of service.

    CVE-2021-37706

        The embedded copy of pjproject is affected by this CVE.
        If the 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 victims machine.

    CVE-2021-43299

        The embedded copy of pjproject is affected by these CVEs.
        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

        The embedded copy of pjproject is affected by these CVEs.
        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

        The embedded copy of pjproject is affected by these CVEs.
        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-2021-43302

        The embedded copy of pjproject is affected by these CVEs.
        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-2021-43303

        The embedded copy of pjproject is affected by these CVEs.
        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-2021-43804

        The embedded copy of pjproject is affected by this CVE.
        In affected versions if the 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.

    CVE-2021-43845

        The embedded copy of pjproject is affected by this CVE.
        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

        The embedded copy of pjproject is affected by this CVE.
        There are various cases where it is possible that certain incoming RTP/RTCP         packets can potentially cause out-of-bound read access.

    CVE-2022-21723

        The embedded copy of pjproject is affected by this CVE.
        Parsing an incoming SIP message that contains a malformed multipart can         potentially cause out-of-bound read access.

    CVE-2022-23537

        The embedded copy of pjproject is affected by this CVE.
        Buffer overread is possible when parsing a specially crafted STUN message         with unknown attribute.

    CVE-2022-23547

        The embedded copy of pjproject is affected by this CVE.
        Possible buffer overread when parsing a certain STUN message.

    CVE-2022-23608

        The embedded copy of pjproject is affected by this CVE.
        When in a dialog set (or forking) scenario, a hash key shared by multiple         UAC dialogs can potentially be prematurely freed when one of the dialogs is         destroyed . The issue may cause a dialog set to be registered in the hash         table multiple times (with different hash keys) leading to undefined         behavior such as dialog list collision which eventually leading to endless         loop.

    CVE-2022-24754

        The embedded copy of pjproject is affected by this CVE.
        There is a stack-buffer overflow vulnerability which only impacts PJSIP         users who accept hashed digest credentials (credentials with data_type         `PJSIP_CRED_DATA_DIGEST`).

    CVE-2022-24763

        The embedded copy of pjproject is affected by this CVE.

        A buffer overflow vulnerability in affects applications that use PJSIP DNS         resolution.

    CVE-2022-31031

        The embedded copy of pjproject is affected by this CVE.
        A stack buffer overflow vulnerability affects PJSIP users that use STUN in         their applications, either by: setting a STUN server in their account/media         config in PJSUA/PJSUA2 level, or directly using `pjlib-util/stun_simple`         API.

    CVE-2022-39244

        The embedded copy of pjproject is affected by this CVE.
        The PJSIP parser, PJMEDIA RTP decoder, and PJMEDIA SDP parser are affeced         by a buffer overflow vulnerability. Users connecting to untrusted clients         are at risk.
