Sun Solaris NFSv4 client kernel module denial of service
| solaris-nfsv4-dos (44546) |  Medium Risk |
Description:
Sun Solaris is vulnerable to a denial of service, caused by an unspecified error in the NFSv4 client kernel module. By working with an authenticated user on an NFSv4 server, a local attacker could cause all local NFSv4 mounts on client systems to become unresponsive.
*CVSS:
| Base Score: | 2.1 |
| Access Vector: | Local |
| Access Complexity: | Low |
| Authentication: | None |
| Confidentiality Impact: | None |
| Integrity Impact: | None |
| Availability Impact: | Partial |
| Temporal Score: | 1.6 |
| Exploitability: | Unproven |
| Remediation Level: | Official-Fix |
| Report Confidence: | Confirmed |
Consequences:
Denial of Service
Remedy:
