Asterisk IAX2 information disclosure
|asterisk-iax2-information-disclosure (34085)||Low Risk|
Asterisk could allow a remote attacker to obtain sensitive information caused by improper handling of text frames by the IAX2 channel driver (chan_iax2). An attacker could send a specially-crafted frame without a NULL terminating byte to cause Asterisk to return arbitrary memory contents.
Refer to ASA-2007-013 for patch, upgrade or suggested workaround information. See References.
For Debian/GNU Linux:
Refer to DSA-1358-1 for patch, upgrade, or suggested workaround information. See References.

- CVE-2007-2488: 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.
