Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Incorrect default permissions (CVE-ID: CVE-2020-17521)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to incorrect default permissions for temporary files and folders that are set by the application. A local user with access to the system can view contents of files and directories or modify them.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-11979)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to incorrect patch for vulnerability #VU27924 (CVE-2020-1945). Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.
