| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2007-08-09 | CVE-2007-4280 | Remote Denial of Service vulnerability in Asterisk Skinny Channel Driver 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. network asterisk | 3.5 |
| 2007-07-18 | CVE-2007-3765 | Remote Denial of Service vulnerability in Asterisk 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. | 5.0 |
| 2007-07-18 | CVE-2007-3764 | Remote Denial of Service vulnerability in Asterisk 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." | 5.0 |
| 2007-07-18 | CVE-2007-3763 | Remote Denial of Service vulnerability in Asterisk 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. | 5.0 |
| 2007-07-18 | CVE-2007-3762 | Remote Stack Buffer Overflow vulnerability in Asterisk IAX2 Channel Driver IAX2_Write Function 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. | 9.3 |
| 2007-05-07 | CVE-2007-2488 | Information Disclosure vulnerability in Asterisk IAX2 Text Frame 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. | 10.0 |
| 2007-04-26 | CVE-2007-2297 | Remote Denial of Service vulnerability in Asterisk SIP Channel Driver UDP Packets 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). | 7.8 |
| 2007-04-26 | CVE-2007-2294 | Remote Denial of Service vulnerability in Asterisk ManagerInterface Manager.Conf 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. | 7.8 |
| 2007-04-26 | CVE-2007-2293 | Remote Stack Buffer Overflow vulnerability in Asterisk 1.4.1/1.4.2/1.4Beta Multiple stack-based buffer overflows in the process_sdp function in chan_sip.c of the SIP channel T.38 SDP parser in Asterisk before 1.4.3 allow remote attackers to execute arbitrary code via a long (1) T38FaxRateManagement or (2) T38FaxUdpEC SDP parameter in an SIP message, as demonstrated using SIP INVITE. | 7.6 |
| 2007-03-22 | CVE-2007-1595 | Unspecified vulnerability in Asterisk 1.2.13 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. | 7.5 |
