Sun Solaris kernel race condition causes denial of service
| solaris-race-dos (13434) |  Low Risk |
Description:
Sun Solaris is vulnerable to a denial of service, caused by a kernel race condition. A local unprivileged attacker can run an application containing code that uses the namefs Mounted pipe function and certain STREAMS routines to cause a denial of service. A system panic may also occur when the Solaris system is acting as a print server and experiences high loads.
Platforms Affected:
- Sun, Solaris 2.6
- Sun, Solaris 7.0
- Sun, Solaris 8
- Sun, Solaris 9
Remedy:
Apply the appropriate patch for your system, as listed below. Refer to Sun Alert ID: 57080 for more information. See References.
