Asterisk Project Security Advisory - AST-2015-003
Posted Apr 9, 2015
Authored by Jonathan Rose | Site asterisk.org

Asterisk Project Security Advisory - When Asterisk registers to a SIP TLS device and and verifies the server, Asterisk will accept signed certificates that match a common name other than the one Asterisk is expecting if the signed certificate has a common name containing a null byte after the portion of the common name that Asterisk expected.

Asterisk Project Security Advisory - The Asterisk module res_pjsip_acl provides the ability to configure ACLs that may be used to reject SIP requests from various hosts. In affected versions of Asterisk, this module fails to create and apply ACLs defined in pjsip.conf. This may be worked around by reloading res_pjsip manually after res_pjsip_acl is loaded.

Asterisk Project Security Advisory - Manager users can execute arbitrary shell commands with the MixMonitor manager action. Asterisk does not require system class authorization for a manager user to use the MixMonitor action, so any manager user who is permitted to use manager commands can potentially execute shell commands as the user executing the Asterisk process.

Asterisk Project Security Advisory - The format attribute resource for h264 video performs an unsafe read against a media attribute when parsing the SDP. The vulnerable parameter can be received as strings of an arbitrary length and Asterisk attempts to read them into limited buffer spaces without applying a limit to the number of characters read. If a message is formed improperly, this could lead to an attacker being able to execute arbitrary code remotely.

Asterisk Project Security Advisory - AST-2012-004

Asterisk Project Security Advisory - A user of the Asterisk Manager Interface can bypass a security check and execute shell commands when they lack permission to do so. Under normal conditions, a user should only be able to run shell commands if that user has System class authorization. Users could bypass this restriction by using the MixMonitor application with the originate action or by using either the GetVar or Status manager actions in combination with the SHELL and EVAL functions. The patch adds checks in each affected action to verify if a user has System class authorization. If the user does not have those authorizations, Asterisk rejects the action if it detects the use of any functions or applications that run system commands.

Asterisk Project Security Advisory - If a remote user initiates a SIP call and the recipient picks up, the remote user can reply with a malformed Contact header that Asterisk will improperly handle and cause a crash due to a segmentation fault.
