Title
DSA-2225-1 asterisk -- several
Description
Several vulnerabilities have been discovered in Asterisk, an Open Source PBX and telephony toolkit. CVE-2011-1147 Matthew Nicholson discovered that incorrect handling of UDPTL packets may lead to denial of service of the execution of arbitrary code. CVE-2011-1174 Blake Cornell discovered that incorrect connection handling in the manager interface may lead to denial of service. CVE-2011-1175 Blake Cornell and Chris May discovered that incorrect TCP connection handling may lead to denial of service. CVE-2011-1507 Tzafrir Cohen discovered that insufficient limitation of connection requests in several TCP based services may lead to denial of service. CVE-2011-1599 Matthew Nicholson discovered a privilege escalation vulnerability in the manager interface.

Comment
: 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.

Comment
: 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.

: 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.
