The remote FreeSWITCH server is affected by a remote code execution
The remote FreeSWITCH server is prior to version 1.4.26 or 1.6.x prior
to 1.6.5. It is, therefore, affected by a remote code execution
vulnerability due to improper validation of user-supplied input to the
parse_string() function in esl_json.c, switch_json.c, and ks_json.c. A
remote attacker can exploit this, via a crafted JSON message, to cause
a heap-based buffer overflow condition, resulting in a denial of
service or the execution of arbitrary code.
