Debian Linux Security Advisory 5438-1 - A flaw was found in Asterisk, an Open Source Private Branch Exchange. A buffer overflow vulnerability affects users that use 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 workaround is to disable DNS resolution in PJSIP config (by setting nameserver_count to zero) or use an external resolver implementation instead.

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. 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.

PJSIP is a free and open source multimedia communication library written in C. In versions of PJSIP prior to 2.13 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. This issue has been patched and is available as commit c4d3498 in the master branch and will be included in releases 2.13 and later. Users are advised to upgrade. There are no known workarounds for this issue.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In versions prior to and including 2.12.1 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. A patch is available in commit 450baca which should be included in the next release. There are no known workarounds for this issue.

PJSIP is a free and open source multimedia communication library written in C. A buffer overflow vulnerability in versions 2.12 and prior affects applications that uses PJSIP DNS resolution. It doesn't affect PJSIP users who utilize an external resolver. A patch is available in the `master` branch of the `pjsip/pjproject` GitHub repository. A workaround is to disable DNS resolution in PJSIP config (by setting `nameserver_count` to zero) or use an external resolver instead.

PJSIP is a free and open source multimedia communication library written in the C language. Versions 2.12 and prior contain a denial-of-service vulnerability that affects PJSIP users that consume PJSIP's XML parsing in their apps. Users are advised to update. There are no known workarounds.

PJSIP is a free and open source multimedia communication library written in C. Versions 2.12 and prior contain a stack buffer overflow vulnerability that affects PJSUA2 users or users that call the API `pjmedia_sdp_print(), pjmedia_sdp_media_print()`. Applications that do not use PJSUA2 and do not directly call `pjmedia_sdp_print()` or `pjmedia_sdp_media_print()` should not be affected. A patch is available on the `master` branch of the `pjsip/pjproject` GitHub repository. There are currently no known workarounds.

PJSIP is a free and open source multimedia communication library written in C language. In versions prior to and including 2.12 PJSIP 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`). This issue has been patched in the master branch of the PJSIP repository and will be included with the next release. Users unable to upgrade need to check that the hashed digest data length must be equal to `PJSIP_MD5STRLEN` before passing to PJSIP.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In versions up to and including 2.11.1 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. A patch is available in commit db3235953baa56d2fb0e276ca510fefca751643f which will be included in the next release. There are no known workarounds for this issue.

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.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In versions 2.11.1 and prior, parsing an incoming SIP message that contains a malformed multipart can potentially cause out-of-bound read access. This issue affects all PJSIP users that accept SIP multipart. The patch is available as commit in the `master` branch. There are no known workarounds.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In version 2.11.1 and prior, there are various cases where 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. A patch is available as a commit in the `master` branch. There are no known workarounds.

PJSIP is a free and open source multimedia communication library. In version 2.11.1 and prior, 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. This affects all users that use PJMEDIA and RTCP XR. A malicious actor can send a RTCP XR message with an invalid packet size.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. 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. This issue affects all users that use PJMEDIA and RTCP. A malicious actor can send a RTCP BYE message with an invalid reason length. Users are advised to upgrade as soon as possible. There are no known workarounds.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions 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 victim’s machine. Users are advised to upgrade as soon as possible. There are no known workarounds.
