Description

This security bulletin contains information about 1 security vulnerability.


1) Missing release of memory after effective lifetime (CVE-ID: CVE-2004-0427)

The vulnerability allows a local user to perform service disruption.

The do_fork function in Linux 2.4.x before 2.4.26, and 2.6.x before 2.6.6, does not properly decrement the mm_count counter when an error occurs after the mm_struct for a child process has been activated, which triggers a memory leak that allows local users to cause a denial of service (memory exhaustion) via the clone (CLONE_VM) system call.


Remediation

Install update from vendor's website.
