CVE-2011-2665 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
reqresp_parser.c in the SIP channel driver in Asterisk Open Source 1.8.x before 1.8.4.3 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a SIP packet with a Contact header that lacks a < (less than) character. | ||||
CVE-2011-2666 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
The default configuration of the SIP channel driver in Asterisk Open Source 1.4.x through 1.4.41.2 and 1.6.2.x through 1.6.2.18.2 does not enable the alwaysauthreject option, which allows remote attackers to enumerate account names by making a series of invalid SIP requests and observing the differences in the responses for different usernames, a different vulnerability than CVE-2011-2536. | ||||
CVE-2011-4597 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
The SIP over UDP implementation in Asterisk Open Source 1.4.x before 1.4.43, 1.6.x before 1.6.2.21, and 1.8.x before 1.8.7.2 uses different port numbers for responses to invalid requests depending on whether a SIP username exists, which allows remote attackers to enumerate usernames via a series of requests. | ||||
CVE-2011-4598 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
The handle_request_info function in channels/chan_sip.c in Asterisk Open Source 1.6.2.x before 1.6.2.21 and 1.8.x before 1.8.7.2, when automon is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted sequence of SIP requests. | ||||
CVE-2012-1183 | 2 Debian, Digium | 2 Debian Linux, Asterisk | 2025-04-11 | N/A |
Stack-based buffer overflow in the milliwatt_generate function in the Miliwatt application in Asterisk 1.4.x before 1.4.44, 1.6.x before 1.6.2.23, 1.8.x before 1.8.10.1, and 10.x before 10.2.1, when the o option is used and the internal_timing option is off, allows remote attackers to cause a denial of service (application crash) via a large number of samples in an audio packet. | ||||
CVE-2012-1184 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
Stack-based buffer overflow in the ast_parse_digest function in main/utils.c in Asterisk 1.8.x before 1.8.10.1 and 10.x before 10.2.1 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string in an HTTP Digest Authentication header. | ||||
CVE-2012-2947 | 2 Debian, Digium | 3 Debian Linux, Asterisk, Certified Asterisk | 2025-04-11 | N/A |
chan_iax2.c in the IAX2 channel driver in Certified Asterisk 1.8.11-cert before 1.8.11-cert2 and Asterisk Open Source 1.8.x before 1.8.12.1 and 10.x before 10.4.1, when a certain mohinterpret setting is enabled, allows remote attackers to cause a denial of service (daemon crash) by placing a call on hold. | ||||
CVE-2007-6171 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
SQL injection vulnerability in the Postgres Realtime Engine (res_config_pgsql) in Asterisk 1.4.x before 1.4.15 and C.x before C.1.0-beta6 allows remote attackers to execute arbitrary SQL commands via unknown vectors. | ||||
CVE-2006-5444 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
Integer overflow in the get_input function in the Skinny channel driver (chan_skinny.c) in Asterisk 1.0.x before 1.0.12 and 1.2.x before 1.2.13, as used by Cisco SCCP phones, allows remote attackers to execute arbitrary code via a certain dlen value that passes a signed integer comparison and leads to a heap-based buffer overflow. | ||||
CVE-2006-5445 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
Unspecified vulnerability in the SIP channel driver (channels/chan_sip.c) in Asterisk 1.2.x before 1.2.13 and 1.4.x before 1.4.0-beta3 allows remote attackers to cause a denial of service (resource consumption) via unspecified vectors that result in the creation of "a real pvt structure" that uses more resources than necessary. | ||||
CVE-2007-1306 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
Asterisk 1.4 before 1.4.1 and 1.2 before 1.2.16 allows remote attackers to cause a denial of service (crash) by sending a Session Initiation Protocol (SIP) packet without a URI and SIP-version header, which results in a NULL pointer dereference. | ||||
CVE-2007-4103 | 1 Digium | 2 Asterisk, Asterisk Appliance Developer Kit | 2025-04-09 | 7.5 High |
The IAX2 channel driver (chan_iax2) in Asterisk Open 1.2.x before 1.2.23, 1.4.x before 1.4.9, and Asterisk Appliance Developer Kit before 0.6.0, when configured to allow unauthenticated calls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of calls that do not complete a 3-way handshake, which causes an ast_channel to be allocated but not released. | ||||
CVE-2007-5358 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
Multiple buffer overflows in the voicemail functionality in Asterisk 1.4.x before 1.4.13, when using IMAP storage, might allow (1) remote attackers to execute arbitrary code via a long combination of Content-type and Content-description headers, or (2) local users to execute arbitrary code via a long combination of astspooldir, voicemail context, and voicemail mailbox fields. NOTE: vector 2 requires write access to Asterisk configuration files. | ||||
CVE-2007-6170 | 2 Debian, Digium | 2 Debian Linux, Asterisk | 2025-04-09 | N/A |
SQL injection vulnerability in the Call Detail Record Postgres logging engine (cdr_pgsql) in Asterisk 1.4.x before 1.4.15, 1.2.x before 1.2.25, B.x before B.2.3.4, and C.x before C.1.0-beta6 allows remote authenticated users to execute arbitrary SQL commands via (1) ANI and (2) DNIS arguments. | ||||
CVE-2009-0871 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
The SIP channel driver in Asterisk Open Source 1.4.22, 1.4.23, and 1.4.23.1; 1.6.0 before 1.6.0.6; 1.6.1 before 1.6.1.0-rc2; and Asterisk Business Edition C.2.3, with the pedantic option enabled, allows remote authenticated users to cause a denial of service (crash) via a SIP INVITE request without any headers, which triggers a NULL pointer dereference in the (1) sip_uri_headers_cmp and (2) sip_uri_params_cmp functions. | ||||
CVE-2009-2651 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
main/rtp.c in Asterisk Open Source 1.6.1 before 1.6.1.2 allows remote attackers to cause a denial of service (crash) via an RTP text frame without a certain delimiter, which triggers a NULL pointer dereference and the subsequent calculation of an invalid pointer. | ||||
CVE-2009-2726 | 1 Digium | 3 Asterisk, S800i, S800i Firmware | 2025-04-09 | N/A |
The SIP channel driver in Asterisk Open Source 1.2.x before 1.2.34, 1.4.x before 1.4.26.1, 1.6.0.x before 1.6.0.12, and 1.6.1.x before 1.6.1.4; Asterisk Business Edition A.x.x, B.x.x before B.2.5.9, C.2.x before C.2.4.1, and C.3.x before C.3.1; and Asterisk Appliance s800i 1.2.x before 1.3.0.3 does not use a maximum width when invoking sscanf style functions, which allows remote attackers to cause a denial of service (stack memory consumption) via SIP packets containing large sequences of ASCII decimal characters, as demonstrated via vectors related to (1) the CSeq value in a SIP header, (2) large Content-Length value, and (3) SDP. | ||||
CVE-2009-3727 | 1 Digium | 3 Asterisk, Asterisknow, S800i | 2025-04-09 | N/A |
Asterisk Open Source 1.2.x before 1.2.35, 1.4.x before 1.4.26.3, 1.6.0.x before 1.6.0.17, and 1.6.1.x before 1.6.1.9; Business Edition A.x.x, B.x.x before B.2.5.12, C.2.x.x before C.2.4.5, and C.3.x.x before C.3.2.2; AsteriskNOW 1.5; and s800i 1.3.x before 1.3.0.5 generate different error messages depending on whether a SIP username is valid, which allows remote attackers to enumerate valid usernames via multiple crafted REGISTER messages with inconsistent usernames in the URI in the To header and the Digest in the Authorization header. | ||||
CVE-2009-4055 | 1 Digium | 2 Asterisk, S800i | 2025-04-09 | N/A |
