Linux Kernel ELF loader denial of service
| linux-kernel-elfloader-dos (43124) |  Low Risk |
Description:
Linux Kernel is vulnerable to a denial of service, caused by an unspecified error in the ELF object file loader. By sending a specially-crafted ELF file containing an interpreter with an invalid architecture, a local attacker could exploit this vulnerability to cause the system to crash.
*CVSS:
| Base Score: | 2.5 |
| Access Vector: | Local |
| Access Complexity: | Low |
| Authentication: | Not Required |
| Confidentiality Impact: | None |
| Integrity Impact: | None |
| Availability Impact: | Partial |
| Temporal Score: | 1.8 |
| Exploitability: | Unproven |
| Remediation Level: | Official-Fix |
| Report Confidence: | Confirmed |
Consequences:
Denial of Service
Remedy:
Upgrade to the latest version of Linux Kernel (2.4.25 or later), available from The Linux Kernel Archives Web site. See References.
