| 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-2007-3763 | 1 Asterisk | 4 Asterisk, Asterisk Appliance Developer Kit, Asterisknow and 1 more | 2025-04-09 | N/A |
| 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 cause a denial of service (crash) via a crafted (1) LAGRQ or (2) LAGRP frame that contains information elements of IAX frames, which results in a NULL pointer dereference when Asterisk does not properly set an associated variable. | ||||
| 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-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. | ||||
