Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Leveraging Race Conditions This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
- Leveraging Race Conditions via Symbolic Links This attack leverages the use of symbolic links (Symlinks) in order to write to sensitive files. An attacker can create a Symlink link to a target file not otherwise accessible to her. When the privileged program tries to create a temporary file with the same name as the Symlink link, it will actually write to the target file pointed to by the attackers' Symlink link. If the attacker can insert malicious content in the temporary file she will be writing to the sensitive file by using the Symlink. The race occurs because the system checks if the temporary file exists, then creates the file. The attacker would typically create the Symlink during the interval between the check and the creation of the temporary file.

description | Updated dump packages that address two security issues are now available for Red Hat Enterprise Linux 2.1. This update has been rated as having low security impact by the Red Hat Security Response Team. Dump examines files in a file system, determines which ones need to be backed up, and copies those files to a specified disk, tape, or other storage medium. A flaw was found with dump file locking. A malicious local user could manipulate the file lock in such a way as to prevent dump from running. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2002-1914 to this issue. Users of dump should upgrade to these erratum packages, which contain a patch to resolve this issue. |
