CVE-2011-1507 Asterisk: file descriptor resource exhaustion (AST-2011-005)

CVE-2011-1507 [MEDIUM] CVE-2011-1507 Asterisk: file descriptor resource exhaustion (AST-2011-005)
CVE-2011-1507 Asterisk: file descriptor resource exhaustion (AST-2011-005)
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).
