| 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-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-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-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-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-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-2008-5396 | 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-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-2021-37706 | 4 Asterisk, Debian, Sangoma and 1 more | 4 Certified Asterisk, Debian Linux, Asterisk and 1 more | 2024-11-21 | 7.3 High |
| PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming STUN message contains an ERROR-CODE attribute, the header length is not checked before performing a subtraction operation, potentially resulting in an integer underflow scenario. This issue affects all users that use STUN. A malicious actor located within the victim’s network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victim’s machine. Users are advised to upgrade as soon as possible. There are no known workarounds. | ||||
| 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. | ||||
| CVE-2024-42365 | 1 Asterisk | 2 Asterisk, Certified Asterisk | 2024-09-16 | 7.4 High |
| Asterisk is an open source private branch exchange (PBX) and telephony toolkit. Prior to asterisk versions 18.24.2, 20.9.2, and 21.4.2 and certified-asterisk versions 18.9-cert11 and 20.7-cert2, an AMI user with `write=originate` may change all configuration files in the `/etc/asterisk/` directory. This occurs because they are able to curl remote files and write them to disk, but are also able to append to existing files using the `FILE` function inside the `SET` application. This issue may result in privilege escalation, remote code execution and/or blind server-side request forgery with arbitrary protocol. Asterisk versions 18.24.2, 20.9.2, and 21.4.2 and certified-asterisk versions 18.9-cert11 and 20.7-cert2 contain a fix for this issue. | ||||
