CVE-2007-2488 (CCN-34085)

Assigned:2007-05-04
Published:2007-05-04
Updated:2017-07-29
Summary:The IAX2 channel driver (chan_iax2) in Asterisk before 20070504 does not properly null terminate data, which allows remote attackers to trigger loss of transmitted data, and possibly obtain sensitive information (memory contents) or cause a denial of service (application crash), by sending a frame that lacks a 0 byte.
