Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2962 advisory.

Multiple security issues were discovered in pjproject, is a free and open source multimedia communication library. 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 victims network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victims 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 multipart can potentially cause out-of-bound read access. This issue affects all PJSIP users that accept SIP multipart. CVE-2022-23608 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 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-2022-24764 A stack buffer overflow vulnerability that affects PJSUA2 users or users that call the API `pjmedia_sdp_print(), pjmedia_sdp_media_print()` For Debian 9 stretch, these problems have been fixed in version 2.5.5~dfsg-6+deb9u3.
