EUVDB-ID: #VU95641

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2005-0003

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local user to perform service disruption.

The 64 bit ELF support in Linux kernel 2.6 before 2.6.10, on 64-bit architectures, does not properly check for overlapping VMA (virtual memory address) allocations, which allows local users to cause a denial of service (system crash) or execute arbitrary code via a crafted ELF or a.out file.

Mitigation

Install update from vendor's repository.
