| CVE-2021-26712 | 1 Digium | 2 Asterisk, Certified Asterisk | 2021-02-24 | 5.0 MEDIUM | 7.5 HIGH |
| Incorrect access controls in res_srtp.c in Sangoma Asterisk 13.38.1, 16.16.0, 17.9.1, and 18.2.0 and Certified Asterisk 16.8-cert5 allow a remote unauthenticated attacker to prematurely terminate secure calls by replaying SRTP packets. | |||||
| CVE-2021-26906 | 1 Digium | 2 Asterisk, Certified Asterisk | 2021-02-24 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue was discovered in res_pjsip_session.c in Digium Asterisk through 13.38.1; 14.x, 15.x, and 16.x through 16.16.0; 17.x through 17.9.1; and 18.x through 18.2.0, and Certified Asterisk through 16.8-cert5.

| An issue was discovered in res_pjsip_diversion.c in Sangoma Asterisk before 13.38.0, 14.x through 16.x before 16.15.0, 17.x before 17.9.0, and 18.x before 18.1.0. A crash can occur when a SIP message is received with a History-Info header that contains a tel-uri, or when a SIP 181 response is received that contains a tel-uri in the Diversion header. | |||||
| CVE-2012-1183 | 2 Debian, Digium | 2 Debian Linux, Asterisk | 2020-08-25 | 4.3 MEDIUM | N/A |
| Stack-based buffer overflow in the milliwatt_generate function in the Miliwatt application in Asterisk 1.4.x before 1.4.44, 1.6.x before 1.6.2.23, 1.8.x before 1.8.10.1, and 10.x before 10.2.1, when the o option is used and the internal_timing option is off, allows remote attackers to cause a denial of service (application crash) via a large number of samples in an audio packet. | |||||
| CVE-2011-0495 | 3 Debian, Digium, Fedoraproject | 6 Debian Linux, Asterisk, Asterisknow and 3 more | 2020-07-15 | 6.0 MEDIUM | N/A |
| Stack-based buffer overflow in the ast_uri_encode function in main/utils.c in Asterisk Open Source before 1.4.38.1, 1.4.39.1, 1.6.1.21, 1.6.2.15.1, 1.6.2.16.1, 1.8.1.2, 1.8.2.; and Business Edition before C.3.6.2; when running in pedantic mode allows remote authenticated users to execute arbitrary code via crafted caller ID data in vectors involving the (1) SIP channel driver, (2) URIENCODE dialplan function, or (3) AGI dialplan function. | |||||
| CVE-2018-7287 | 1 Digium | 1 Asterisk | 2019-10-03 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue was discovered in res_http_websocket.c in Asterisk 15.x through 15.2.1. If the HTTP server is enabled (default is disabled), WebSocket payloads of size 0 are mishandled (with a busy loop). | |||||
| CVE-2018-7286 | 2 Debian, Digium | 3 Debian Linux, Asterisk, Certified Asterisk | 2019-10-03 | 4.0 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Asterisk through 13.19.1, 14.x through 14.7.5, and 15.x through 15.2.1, and Certified Asterisk through 13.18-cert2. res_pjsip allows remote authenticated users to crash Asterisk (segmentation fault) by sending a number of SIP INVITE messages on a TCP or TLS connection and then suddenly closing the connection. | |||||
| CVE-2017-16672 | 1 Digium | 2 Asterisk, Certified Asterisk | 2019-10-03 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue was discovered in Asterisk Open Source 13 before 13.18.1, 14 before 14.7.1, and 15 before 15.1.1 and Certified Asterisk 13.13 before 13.13-cert7. A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed. Eventually Asterisk can run out of memory and crash. | |||||
| CVE-2017-17090 | 1 Digium | 2 Asterisk, Certified Asterisk | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in chan_skinny.c in Asterisk Open Source 13.18.2 and older, 14.7.2 and older, and 15.1.2 and older, and Certified Asterisk 13.13-cert7 and older. If the chan_skinny (aka SCCP protocol) channel driver is flooded with certain requests, it can cause the asterisk process to use excessive amounts of virtual memory, eventually causing asterisk to stop processing requests of any kind. | |||||
| CVE-2018-17281 | 2 Debian, Digium | 3 Debian Linux, Asterisk, Certified Asterisk | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| There is a stack consumption vulnerability in the res_http_websocket.so module of Asterisk through 13.23.0, 14.7.x through 14.7.7, and 15.x through 15.6.0 and Certified Asterisk through 13.21-cert2. It allows an attacker to crash Asterisk via a specially crafted HTTP request to upgrade the connection to a websocket. | |||||
| CVE-2017-14100 | 1 Digium | 2 Asterisk, Certified Asterisk | 2019-10-03 | 7.5 HIGH | 9.8 CRITICAL |
| In Asterisk 11.x before 11.25.2, 13.x before 13.17.1, and 14.x before 14.6.1 and Certified Asterisk 11.x before 11.6-cert17 and 13.x before 13.13-cert5, unauthorized command execution is possible. The app_minivm module has an "externnotify" program configuration option that is executed by the MinivmNotify dialplan application. The application uses the caller-id name and number as part of a built string passed to the OS shell for interpretation and execution. Since the caller-id name and number can come from an untrusted source, a crafted caller-id name or number allows an arbitrary shell command injection. | |||||
| CVE-2019-15639 | 1 Digium | 1 Asterisk | 2019-09-10 | 5.0 MEDIUM | 7.5 HIGH |
| main/translate.c in Sangoma Asterisk 13.28.0 and 16.5.0 allows a remote attacker to send a specific RTP packet during a call and cause a crash in a specific scenario. | |||||
| CVE-2014-8418 | 1 Digium | 2 Asterisk, Certified Asterisk | 2019-07-16 | 9.0 HIGH | N/A |
| The DB dialplan function in Asterisk Open Source 1.8.x before 1.8.32, 11.x before 11.1.4.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 1.8 before 1.8.28-cert8 and 11.6 before 11.6-cert8 allows remote authenticated users to gain privileges via a call from an external protocol, as demonstrated by the AMI protocol. | |||||
| CVE-2014-8417 | 1 Digium | 2 Asterisk, Certified Asterisk | 2019-07-16 | 6.5 MEDIUM | N/A |
| ConfBridge in Asterisk 11.x before 11.14.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 11.6 before 11.6-cert8 allows remote authenticated users to (1) gain privileges via vectors related to an external protocol to the CONFBRIDGE dialplan function or (2) execute arbitrary system commands via a crafted ConfbridgeStartRecord AMI action. | |||||
| CVE-2014-8416 | 1 Digium | 1 Asterisk | 2019-07-16 | 5.0 MEDIUM | N/A |
| Use-after-free vulnerability in the PJSIP channel driver in Asterisk Open Source 12.x before 12.7.1 and 13.x before 13.0.1, when using the res_pjsip_refer module, allows remote attackers to cause a denial of service (crash) via an in-dialog INVITE with Replaces message, which triggers the channel to be hung up. | |||||
| CVE-2014-8415 | 1 Digium | 1 Asterisk | 2019-07-16 | 5.0 MEDIUM | N/A |
| Race condition in the chan_pjsip channel driver in Asterisk Open Source 12.x before 12.7.1 and 13.x before 13.0.1 allows remote attackers to cause a denial of service (assertion failure and crash) via a cancel request for a SIP session with a queued action to (1) answer a session or (2) send ringing. | |||||
| CVE-2014-8413 | 1 Digium | 1 Asterisk | 2019-07-16 | 7.5 HIGH | N/A |
| The res_pjsip_acl module in Asterisk Open Source 12.x before 12.7.1 and 13.x before 13.0.1 does not properly create and load ACLs defined in pjsip.conf at startup, which allows remote attackers to bypass intended PJSIP ACL rules. | |||||
| CVE-2014-8412 | 1 Digium | 2 Asterisk, Certified Asterisk | 2019-07-16 | 5.0 MEDIUM | N/A |
| The (1) VoIP channel drivers, (2) DUNDi, and (3) Asterisk Manager Interface (AMI) in Asterisk Open Source 1.8.x before 1.8.32.1, 11.x before 11.14.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 1.8.28 before 1.8.28-cert3 and 11.6 before 11.6-cert8 allows remote attackers to bypass the ACL restrictions via a packet with a source IP that does not share the address family as the first ACL entry. | |||||
