Multiple security vulnerabilities in Solaris 10 SCTP Socket Option Processing (see sctp(7P)) may allow an unprivileged local user to panic the system, resulting in a Denial of Service (DoS).

These issues can occur in the following releases:

SPARC Platform

• Solaris 10 without patch 119075-09

x86 Platform

• Solaris 10 without patch 119076-08

Note: Solaris 7 will not be evaluated regarding the potential impact of the issue described in this Sun Alert. Solaris 8 and 9 are not impacted by this issue.

The system may panic with a stack trace similar to the following:

    ...
    vpanic()
    sosctp_setsockopt()
    setsockopt()
    ...

There is no workaround. Please see the Resolution section below.

These issues are addressed in the following releases:

SPARC Platform

• Solaris 10 with patch 119075-09 or later

x86 Platform

• Solaris 10 with patch 119076-08 or later
