CVE-2007-4280 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 Open Source before 1.4.10, AsteriskNOW before beta7, Appliance Developer Kit before 0.7.0, and Appliance s800i before 1.0.3 allows remote authenticated users to cause a denial of service (application crash) via a CAPABILITIES_RES_MESSAGE packet with a capabilities count larger than the capabilities_res_message array population.
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.
CVE-2007-4521 1 Asterisk 1 Asterisk 2025-04-09 N/A
Asterisk Open Source 1.4.5 through 1.4.11, when configured to use an IMAP voicemail storage backend, allows remote attackers to cause a denial of service via an e-mail with an "invalid/corrupted" MIME body, which triggers a crash when the recipient listens to voicemail.
CVE-2007-5488 1 Asterisk 1 Asterisk-addons 2025-04-09 N/A
Multiple SQL injection vulnerabilities in cdr_addon_mysql in Asterisk-Addons before 1.2.8, and 1.4.x before 1.4.4, allow remote attackers to execute arbitrary SQL commands via the (1) source and (2) destination numbers, and probably (3) SIP URI, when inserting a record.
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-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.
CVE-2020-28242 4 Asterisk, Debian, Fedoraproject and 1 more 4 Certified Asterisk, Debian Linux, Fedora and 1 more 2024-11-21 6.5 Medium
An issue was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1 and Certified Asterisk before 16.8-cert5. If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur.
