A Security Vulnerability in Solaris 10 Involving the SCTP Protocol May Result in a Panic and Denial of Service (DoS)

1. Impact

A security vulnerability in Solaris 10 related to the SCTP protocol may allow a local or remote unprivileged user to cause a system panic resulting in a Denial of Service (DoS) condition. (See also sctp(7P)).

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform
  • Solaris 10 without patch 127127-08

Note: Solaris 8 and 9 are not affected by this issue.

This issue only affects systems with a "SCTP" socket in the "LISTEN" state. To determine if a host has such a socket, the following command may be used:
$ netstat -an -P sctp | grep LISTEN
If the system does not have any "SCTP" sockets in the "LISTEN" state, it is not vulnerable to this issue.
