CVE-2011-1507

First published: Fri Apr 22 2011(Updated: )

Asterisk did not limit the number of unauthenticated connections to vulnerable interfaces and did not limit the time unauthenticated clients remain connected to some interfaces. A remote attacker could open many subsequent connections to vulnerable Asterisk interfaces, leading to file descriptor resource exhaustion or possibly to disk space exhaustion (due Asterisk feature of logging failures to open new file descriptors into its log file).
