| CVE-2007-1595 | 1 Asterisk | 1 Asterisk | 2025-04-09 | N/A |
| The Asterisk Extension Language (AEL) in pbx/pbx_ael.c in Asterisk does not properly generate extensions, which allows remote attackers to execute arbitrary extensions and have an unknown impact by specifying an invalid extension in a certain form. | ||||
| CVE-2007-2294 | 1 Asterisk | 1 Asterisk | 2025-04-09 | N/A |
| 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-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-2007-3764 | 1 Asterisk | 4 Asterisk, Asterisk Appliance Developer Kit, Asterisknow and 1 more | 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-2007-6430 | 1 Asterisk | 2 Asterisk Business Edition, Open Source | 2025-04-09 | N/A |
| Asterisk Open Source 1.2.x before 1.2.26 and 1.4.x before 1.4.16, and Business Edition B.x.x before B.2.3.6 and C.x.x before C.1.0-beta8, when using database-based registrations ("realtime") and host-based authentication, does not check the IP address when the username is correct and there is no password, which allows remote attackers to bypass authentication using a valid username. | ||||
| 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-2008-2119 | 1 Asterisk | 2 Asterisk Business Edition, Open Source | 2025-04-09 | N/A |
| Asterisk Open Source 1.0.x and 1.2.x before 1.2.29 and Business Edition A.x.x and B.x.x before B.2.5.3, when pedantic parsing (aka pedanticsipchecking) is enabled, allows remote attackers to cause a denial of service (daemon crash) via a SIP INVITE message that lacks a From header, related to invocations of the ast_uri_decode function, and improper handling of (1) an empty const string and (2) a NULL pointer. | ||||
| CVE-2008-1390 | 1 Asterisk | 5 Asterisk, Asterisk Appliance Developer Kit, Asterisk Business Edition and 2 more | 2025-04-09 | N/A |
| The AsteriskGUI HTTP server in Asterisk Open Source 1.4.x before 1.4.19-rc3 and 1.6.x before 1.6.0-beta6, Business Edition C.x.x before C.1.6, AsteriskNOW before 1.0.2, Appliance Developer Kit before revision 104704, and s800i 1.0.x before 1.1.0.2 generates insufficiently random manager ID values, which makes it easier for remote attackers to hijack a manager session via a series of ID guesses. | ||||
| 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-2007-3762 | 1 Asterisk | 4 Asterisk, Asterisk Appliance Developer Kit, Asterisknow and 1 more | 2025-04-09 | N/A |
| Stack-based buffer overflow in the IAX2 channel driver (chan_iax2) 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 execute arbitrary code by sending a long (1) voice or (2) video RTP frame. | ||||
| CVE-2009-2346 | 2 Asterisk, Sangoma | 5 Appliance S800i, Asterisk, Open Source and 2 more | 2025-04-09 | N/A |
| The IAX2 protocol implementation in Asterisk Open Source 1.2.x before 1.2.35, 1.4.x before 1.4.26.2, 1.6.0.x before 1.6.0.15, and 1.6.1.x before 1.6.1.6; Business Edition B.x.x before B.2.5.10, C.2.x before C.2.4.3, and C.3.x before C.3.1.1; and s800i 1.3.x before 1.3.0.3 allows remote attackers to cause a denial of service (call-number exhaustion) by initiating many IAX2 message exchanges, a related issue to CVE-2008-3263. | ||||
| 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-2008-1923 | 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 1.2 before revision 72630 and 1.4 before revision 65679, when configured to allow unauthenticated calls, sends "early audio" to an unverified source IP address of a NEW message, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed NEW message. | ||||
| CVE-2008-1333 | 1 Asterisk | 1 Open Source | 2025-04-09 | N/A |
| Format string vulnerability in Asterisk Open Source 1.6.x before 1.6.0-beta6 might allow remote attackers to execute arbitrary code via logging messages that are not properly handled by (1) the ast_verbose logging API call, or (2) the astman_append function. | ||||
| 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. | ||||
| 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-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-2007-1561 | 1 Asterisk | 1 Asterisk | 2025-04-09 | N/A |
| The channel driver in Asterisk before 1.2.17 and 1.4.x before 1.4.2 allows remote attackers to cause a denial of service (crash) via a SIP INVITE message with an SDP containing one valid and one invalid IP address. | ||||
| CVE-2021-46837 | 3 Asterisk, Debian, Digium | 3 Certified Asterisk, Debian Linux, Asterisk | 2024-11-21 | 6.5 Medium |
| res_pjsip_t38 in Sangoma Asterisk 16.x before 16.16.2, 17.x before 17.9.3, and 18.x before 18.2.2, and Certified Asterisk before 16.8-cert7, allows an attacker to trigger a crash by sending an m=image line and zero port in a response to a T.38 re-invite initiated by Asterisk. This is a re-occurrence of the CVE-2019-15297 symptoms but not for exactly the same reason. The crash occurs because there is an append operation relative to the active topology, but this should instead be a replace operation. | ||||
