CVE-2023-27585
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 victim’s 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 denial-of-service vulnerability affects PJSIP users that consume PJSIP's
XML parsing in their apps.
CVE-2022-24764
The embedded copy of pjproject is affected by this CVE.
A stack buffer overflow vulnerability affects PJSUA2 users or users that
call the API `pjmedia_sdp_print(), pjmedia_sdp_media_print()`.
CVE-2022-24793
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.
CVE-2023-27585
The embedded copy of pjproject is affected by this CVE.
A buffer overflow vulnerability affects applications that use PJSIP DNS
resolver.
For Debian 11 bullseye, these problems have been fixed in version
20210112.2.b757bac~ds1-1+deb11u1.
