Description
This security bulletin contains information about 1 security vulnerability.
1) Improper input validation (CVE-ID: CVE-2004-0138)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The ELF loader in Linux kernel 2.4 before 2.4.25 allows local users to cause a denial of service (crash) via a crafted ELF file with an interpreter with an invalid arch (architecture), which triggers a BUG() when an invalid VMA is unmapped.
Remediation
Install update from vendor's website.
