Name of the Vulnerable Software and Affected Versions Hadoop version 1.0.3

Description The issue arises from Hadoop storing pid files in the shared /tmp directory by default, leading to a symlink vulnerability.

Recommendations For Hadoop version 1.0.3, consider changing the default directory for storing pid files to a more secure location to mitigate the risk of exploitation. As a temporary workaround, restrict access to the /tmp directory to minimize the risk of symlink attacks.
