Asterisk Logger and Manager Format String Vulnerability
------------------------------------------------------------------------


SUMMARY

Logging messages displayed using the Asterisk ast_verbose logging API call
are not displayed as a character string, they are displayed as a format
string. Output as a result of the Manager command "command" is not
appended to the resulting response message as a character string, it is
appended as a format string. It is possible in both instances for an
attacker to provide a formatted string as a value for input which can
cause a crash.

DETAILS

Vulnerable Systems:
* Asterisk Open Source versions prior to 1.6.0-beta6

Immune Systems:
* Asterisk Open Source version 1.6.0-beta6

Resolution:
Input given to both the ast_verbose logging API call and astman_append
function is now interpreted as a character string and not as a format
string.
