| CVE-2013-2686 | 1 Asterisk | 3 Certified Asterisk, Digiumphones, Open Source | 2025-04-11 | N/A |
| main/http.c in the HTTP server in Asterisk Open Source 1.8.x before 1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15 before 1.8.15-cert2; and Asterisk Digiumphones 10.x-digiumphones before 10.12.2-digiumphones does not properly restrict Content-Length values, which allows remote attackers to conduct stack-consumption attacks and cause a denial of service (daemon crash) via a crafted HTTP POST request. NOTE: this vulnerability exists because of an incorrect fix for CVE-2012-5976. | ||||

| chan_skinny.c in the Skinny (aka SCCP) channel driver in Certified Asterisk 1.8.11-cert before 1.8.11-cert2 and Asterisk Open Source 1.8.x before 1.8.12.1 and 10.x before 10.4.1 allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by closing a connection in off-hook mode. | ||||
| CVE-2008-5396 | 1 Asterisk | 1 Zaptel | 2025-04-09 | N/A |
| Array index error in the (1) torisa.c and (2) dahdi/tor2.c drivers in Zaptel (aka DAHDI) 1.4.11 and earlier allows local users in the dialout group to overwrite an integer value in kernel memory by writing to /dev/zap/ctl, related to missing validation of the sync field associated with the ZT_SPANCONFIG ioctl. | ||||
| CVE-2008-5558 | 1 Asterisk | 2 Asterisk Business Edition, Open Source | 2025-04-09 | N/A |
| Asterisk Open Source 1.2.26 through 1.2.30.3 and Business Edition B.2.3.5 through B.2.5.5, when realtime IAX2 users are enabled, allows remote attackers to cause a denial of service (crash) via authentication attempts involving (1) an unknown user or (2) a user using hostname matching. | ||||
| CVE-2008-0095 | 1 Asterisk | 5 Asterisk Appliance Developer Kit, Asterisk Business Edition, Asterisknow and 2 more | 2025-04-09 | N/A |
| The SIP channel driver in Asterisk Open Source 1.4.x before 1.4.17, Business Edition before C.1.0-beta8, AsteriskNOW before beta7, Appliance Developer Kit before Asterisk 1.4 revision 95946, and Appliance s800i 1.0.x before 1.0.3.4 allows remote attackers to cause a denial of service (daemon crash) via a BYE message with an Also (Also transfer) header, which triggers a NULL pointer dereference. | ||||
| CVE-2009-0041 | 1 Asterisk | 3 Asterisk Business Edition, Open Source, S800i Appliance | 2025-04-09 | N/A |
| IAX2 in Asterisk Open Source 1.2.x before 1.2.31, 1.4.x before 1.4.23-rc4, and 1.6.x before 1.6.0.3-rc2; Business Edition A.x.x, B.x.x before B.2.5.7, C.1.x.x before C.1.10.4, and C.2.x.x before C.2.1.2.1; and s800i 1.2.x before 1.3.0 responds differently to a failed login attempt depending on whether the user account exists, which allows remote attackers to enumerate valid usernames. | ||||

| The Manager Interface in Asterisk before 1.2.18 and 1.4.x before 1.4.3 allows remote attackers to cause a denial of service (crash) by using MD5 authentication to authenticate a user that does not have a password defined in manager.conf, resulting in a NULL pointer dereference. | ||||
| CVE-2008-3263 | 1 Asterisk | 1 Asterisk | 2025-04-09 | N/A |
| The IAX2 protocol implementation in Asterisk Open Source 1.0.x, 1.2.x before 1.2.30, and 1.4.x before 1.4.21.2; Business Edition A.x.x, B.x.x before B.2.5.4, and C.x.x before C.1.10.3; AsteriskNOW; Appliance Developer Kit 0.x.x; and s800i 1.0.x before 1.2.0.1 allows remote attackers to cause a denial of service (call-number exhaustion and CPU consumption) by quickly sending a large number of IAX2 (IAX) POKE requests. | ||||
| CVE-2007-6430 | 1 Asterisk | 2 Asterisk Business Edition, Open Source | 2025-04-09 | N/A |

| CVE-2007-3765 | 1 Asterisk | 4 Asterisk, Asterisk Appliance Developer Kit, Asterisknow and 1 more | 2025-04-09 | N/A |
| The STUN implementation in Asterisk 1.4.x before 1.4.8, AsteriskNOW before beta7, Appliance Developer Kit before 0.5.0, and s800i before 1.0.2 allows remote attackers to cause a denial of service (crash) via a crafted STUN length attribute in a STUN packet sent on an RTP port. | ||||
| CVE-2007-3764 | 1 Asterisk | 4 Asterisk, Asterisk Appliance Developer Kit, Asterisknow and 1 more | 2025-04-09 | N/A |
| The Skinny channel driver (chan_skinny) in Asterisk before 1.2.22 and 1.4.x before 1.4.8, Business Edition before B.2.2.1, AsteriskNOW before beta7, Appliance Developer Kit before 0.5.0, and s800i before 1.0.2 allows remote attackers to cause a denial of service (crash) via a certain data length value in a crafted packet, which results in an "overly large memcpy." | ||||
| CVE-2007-2488 | 1 Asterisk | 1 Asterisk | 2025-04-09 | N/A |
| The IAX2 channel driver (chan_iax2) in Asterisk before 20070504 does not properly null terminate data, which allows remote attackers to trigger loss of transmitted data, and possibly obtain sensitive information (memory contents) or cause a denial of service (application crash), by sending a frame that lacks a 0 byte. | ||||
| CVE-2008-1897 | 1 Asterisk | 5 Asterisk Appliance Developer Kit, Asterisk Business Edition, Asterisknow and 2 more | 2025-04-09 | N/A |
| The IAX2 channel driver (chan_iax2) in Asterisk Open Source 1.0.x, 1.2.x before 1.2.28, and 1.4.x before 1.4.19.1; Business Edition A.x.x, B.x.x before B.2.5.2, and C.x.x before C.1.8.1; AsteriskNOW before 1.0.3; Appliance Developer Kit 0.x.x; and s800i before 1.1.0.3, when configured to allow unauthenticated calls, does not verify that an ACK response contains a call number matching the server's reply to a NEW message, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed ACK response that does not complete a 3-way handshake. NOTE: this issue exists because of an incomplete fix for CVE-2008-1923. | ||||
| CVE-2007-2297 | 1 Asterisk | 1 Asterisk | 2025-04-09 | N/A |
| The SIP channel driver (chan_sip) in Asterisk before 1.2.18 and 1.4.x before 1.4.3 does not properly parse SIP UDP packets that do not contain a valid response code, which allows remote attackers to cause a denial of service (crash). | ||||
| CVE-2008-2543 | 1 Asterisk | 1 Asterisk-addons | 2025-04-09 | N/A |
| The ooh323 channel driver in Asterisk Addons 1.2.x before 1.2.9 and Asterisk-Addons 1.4.x before 1.4.7 creates a remotely accessible TCP port that is intended solely for localhost communication, and interprets some TCP application-data fields as addresses of memory to free, which allows remote attackers to cause a denial of service (daemon crash) via crafted TCP packets. | ||||
| CVE-2007-5690 | 1 Asterisk | 1 Zaptel | 2025-04-09 | N/A |
| Buffer overflow in sethdlc.c in the Asterisk Zaptel 1.4.5.1 might allow local users to gain privileges via a long device name (interface name) in the ifr_name field. NOTE: the vendor disputes this issue, stating that the application requires root access, so privilege boundaries are not crossed | ||||
| CVE-2008-5744 | 1 Asterisk | 1 Zaptel | 2025-04-09 | N/A |
| Array index error in the dahdi/tor2.c driver in Zaptel (aka DAHDI) 1.4.11 and earlier allows local users in the dialout group to overwrite an integer value in kernel memory by writing to /dev/zap/ctl, related to an incorrect tor2 patch for CVE-2008-5396 that uses the wrong variable in a range check against the value of lc->sync. | ||||
| CVE-2007-4455 | 1 Asterisk | 3 Asterisk, Asterisk Appliance Developer Kit, Asterisknow | 2025-04-09 | N/A |
| The SIP channel driver (chan_sip) in Asterisk Open Source 1.4.x before 1.4.11, AsteriskNOW before beta7, Asterisk Appliance Developer Kit 0.x before 0.8.0, and s800i (Asterisk Appliance) 1.x before 1.0.3 allows remote attackers to cause a denial of service (memory exhaustion) via a SIP dialog that causes a large number of history entries to be created. | ||||
