| CVE-2012-3553 | 1 Digium | 1 Asterisk | 2012-06-25 | 4.0 MEDIUM | N/A |
| chan_skinny.c in the Skinny (aka SCCP) channel driver in Asterisk Open Source 10.x before 10.5.1 allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by sending a Station Key Pad Button message and closing a connection in off-hook mode, a related issue to CVE-2012-2948. | |||||
| CVE-2011-2536 | 1 Digium | 1 Asterisk | 2011-09-06 | 5.0 MEDIUM | N/A |
| chan_sip.c in the SIP channel driver in Asterisk Open Source 1.4.x before 1.4.41.2, 1.6.2.x before 1.6.2.18.2, and 1.8.x before 1.8.4.4, and Asterisk Business Edition C.3.x before C.3.7.3, disregards the alwaysauthreject option and generates different responses for invalid SIP requests depending on whether the user account exists, which allows remote attackers to enumerate account names via a series of requests. | |||||
| CVE-2011-2665 | 1 Digium | 1 Asterisk | 2011-09-06 | 5.0 MEDIUM | 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-2011-1507 | 1 Digium | 1 Asterisk | 2011-09-06 | 5.0 MEDIUM | N/A |
| Asterisk Open Source 1.4.x before 1.4.40.1, 1.6.1.x before 1.6.1.25, 1.6.2.x before 1.6.2.17.3, and 1.8.x before 1.8.3.3 and Asterisk Business Edition C.x.x before C.3.6.4 do not restrict the number of unauthenticated sessions to certain interfaces, which allows remote attackers to cause a denial of service (file descriptor exhaustion and disk space exhaustion) via a series of TCP connections. | |||||
| CVE-2011-1599 | 1 Digium | 1 Asterisk | 2011-09-06 | 9.0 HIGH | N/A |
| manager.c in the Manager Interface in Asterisk Open Source 1.4.x before 1.4.40.1, 1.6.1.x before 1.6.1.25, 1.6.2.x before 1.6.2.17.3, and 1.8.x before 1.8.3.3 and Asterisk Business Edition C.x.x before C.3.6.4 does not properly check for the system privilege, which allows remote authenticated users to execute arbitrary commands via an Originate action that has an Async header in conjunction with an Application header. | |||||
| CVE-2011-1147 | 1 Digium | 3 Asterisk, Asterisknow, S800i | 2011-08-23 | 6.8 MEDIUM | N/A |
| Multiple stack-based and heap-based buffer overflows in the (1) decode_open_type and (2) udptl_rx_packet functions in main/udptl.c in Asterisk Open Source 1.4.x before 1.4.39.2, 1.6.1.x before 1.6.1.22, 1.6.2.x before 1.6.2.16.2, and 1.8 before 1.8.2.4; Business Edition C.x.x before C.3.6.3; AsteriskNOW 1.5; and s800i (Asterisk Appliance), when T.38 support is enabled, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted UDPTL packet. | |||||
| CVE-2006-1827 | 1 Digium | 1 Asterisk | 2011-03-07 | 6.4 MEDIUM | N/A |
| Integer signedness error in format_jpeg.c in Asterisk 1.2.6 and earlier allows remote attackers to execute arbitrary code via a length value that passes a length check as a negative number, but triggers a buffer overflow when it is used as an unsigned length. | |||||
| CVE-2009-3727 | 1 Digium | 3 Asterisk, Asterisknow, S800i | 2009-12-22 | 5.0 MEDIUM | 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-2003-0779 | 1 Digium | 1 Asterisk | 2008-09-10 | 7.5 HIGH | N/A |
| SQL injection vulnerability in the Call Detail Record (CDR) logging functionality for Asterisk allows remote attackers to execute arbitrary SQL via a CallerID string. | |||||
| CVE-2003-0761 | 1 Digium | 1 Asterisk | 2008-09-05 | 7.5 HIGH | N/A |
| Buffer overflow in the get_msg_text of chan_sip.c in the Session Initiation Protocol (SIP) protocol implementation for Asterisk releases before August 15, 2003, allows remote attackers to execute arbitrary code via certain (1) MESSAGE or (2) INFO requests. | |||||
