Fedora Update Notification
FEDORA-2014-15621
2014-11-22 19:57:26
——————————————————————————–

Name : asterisk
Product : Fedora 21
Version : 11.14.1
Release : 1.fc21
URL : http://www.asterisk.org/
Summary : The Open Source PBX
Description :
Asterisk is a complete PBX in software. It runs on Linux and provides
all of the features you would expect from a PBX and more. Asterisk
does voice over IP in three protocols, and can interoperate with
almost all standards-based telephony equipment using relatively
inexpensive hardware.

——————————————————————————–
Update Information:

* Fri Nov 21 2014 Jeffrey C. Ollie <jeff@ocjtech.us> – 11.14.1-1
– The Asterisk Development Team has announced security releases for Certified
– Asterisk 1.8.28 and 11.6 and Asterisk 1.8, 11, 12, and 13. The available
– security releases are released as versions 1.8.28-cert3, 11.6-cert8, 1.8.32.1,
– 11.14.1, 12.7.1, and 13.0.1.

– These releases are available for immediate download at
– http://downloads.asterisk.org/pub/telephony/asterisk/releases

– The release of these versions resolves the following security vulnerabilities:

– * AST-2014-012: Unauthorized access in the presence of ACLs with mixed IP
– address families

– Many modules in Asterisk that service incoming IP traffic have ACL options
– (“permit” and “deny”) that can be used to whitelist or blacklist address
– ranges. A bug has been discovered where the address family of incoming
– packets is only compared to the IP address family of the first entry in the
– list of access control rules. If the source IP address for an incoming
– packet is not of the same address as the first ACL entry, that packet
– bypasses all ACL rules.

– * AST-2014-018: Permission Escalation through DB dialplan function

– The DB dialplan function when executed from an external protocol, such as AMI,
– could result in a privilege escalation. Users with a lower class authorization
– in AMI can access the internal Asterisk database without the required SYSTEM
– class authorization.

– In addition, the release of 11.6-cert8 and 11.14.1 resolves the following
– security vulnerability:

– * AST-2014-014: High call load with ConfBridge can result in resource exhaustion

– The ConfBridge application uses an internal bridging API to implement
– conference bridges. This internal API uses a state model for channels within
– the conference bridge and transitions between states as different things
– occur. Unload load it is possible for some state transitions to be delayed
– causing the channel to transition from being hung up to waiting for media. As
– the channel has been hung up remotely no further media will arrive and the
– channel will stay within ConfBridge indefinitely.

– In addition, the release of 11.6-cert8, 11.14.1, 12.7.1, and 13.0.1 resolves
– the following security vulnerability:

– * AST-2014-017: Permission Escalation via ConfBridge dialplan function and
– AMI ConfbridgeStartRecord Action

– The CONFBRIDGE dialplan function when executed from an external protocol (such
– as AMI) can result in a privilege escalation as certain options within that
– function can affect the underlying system. Additionally, the AMI
– ConfbridgeStartRecord action has options that would allow modification of the
– underlying system, and does not require SYSTEM class authorization in AMI.

– Finally, the release of 12.7.1 and 13.0.1 resolves the following security
– vulnerabilities:

– * AST-2014-013: Unauthorized access in the presence of ACLs in the PJSIP stack

– The Asterisk module res_pjsip provides the ability to configure ACLs that may
– be used to reject SIP requests from various hosts. However, the module
– currently fails to create and apply the ACLs defined in its configuration
– file on initial module load.

– * AST-2014-015: Remote crash vulnerability in PJSIP channel driver

– The chan_pjsip channel driver uses a queue approach for relating to SIP
– sessions. There exists a race condition where actions may be queued to answer
– a session or send ringing after a SIP session has been terminated using a
– CANCEL request. The code will incorrectly assume that the SIP session is still
– active and attempt to send the SIP response. The PJSIP library does not
– expect the SIP session to be in the disconnected state when sending the
– response and asserts.

– * AST-2014-016: Remote crash vulnerability in PJSIP channel driver

– When handling an INVITE with Replaces message the res_pjsip_refer module
– incorrectly assumes that it will be operating on a channel that has just been
– created. If the INVITE with Replaces message is sent in-dialog after a session
– has been established this assumption will be incorrect. The res_pjsip_refer
– module will then hang up a channel that is actually owned by another thread.
– When this other thread attempts to use the just hung up channel it will end up
– using a freed channel which will likely result in a crash.

– For more information about the details of these vulnerabilities, please read
– security advisories AST-2014-012, AST-2014-013, AST-2014-014, AST-2014-015,
– AST-2014-016, AST-2014-017, and AST-2014-018, which were released at the same
– time as this announcement.
