Sun Solaris rpc.rwalld format string
|solaris-rwall-format-string (8971)||High Risk|
Sun Solaris could allow a remote attacker to execute arbitrary code on the system, caused by a format string vulnerability in the rwall daemon (rpc.rwalld). The rwall daemon is a utility that listens for remote wall requests on a network. A remote attacker could send a specially-crafted format string to rwall to exploit an insecure syslog() call that would allow the attacker to execute arbitrary code on the system with root privileges.
Apply the appropriate patch for your system, as listed in Sun Alert ID: 44502. See References.
