A use-after-free vulnerability exists in the JavaScript engine of Foxit Software’s PDF Reader, version 12.1.2.15332. By prematurely deleting objects associated with pages, a specially crafted PDF document can trigger the reuse of previously freed memory, which can lead to arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

A type confusion vulnerability exists in the Javascript checkThisBox method as implemented in Foxit Reader 12.1.2.15332. A specially-crafted Javascript code inside a malicious PDF document can cause memory corruption and lead to remote code execution. User would need to open a malicious file to trigger the vulnerability.

Deserialization of Untrusted Data vulnerability in Apache ShardingSphere-Agent, which allows attackers to execute arbitrary code by constructing a special YAML configuration file. The attacker needs to have permission to modify the ShardingSphere Agent YAML configuration file on the target machine, and the target machine can access the URL with the arbitrary code JAR. An attacker can use SnakeYAML to deserialize java.net.URLClassLoader and make it load a JAR from a specified URL, and then deserialize javax.script.ScriptEngineManager to load code using that ClassLoader. When the ShardingSphere JVM process starts and uses the ShardingSphere-Agent, the arbitrary code specified by the attacker will be executed during the deserialization of the YAML configuration file by the Agent. This issue affects ShardingSphere-Agent: through 5.3.2. This vulnerability is fixed in Apache ShardingSphere 5.4.0.

Vulnerability in the Oracle Hyperion Financial Reporting product of Oracle Hyperion (component: Repository). The supported version that is affected is 11.2.13.0.000. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Financial Reporting. While the vulnerability is in Oracle Hyperion Financial Reporting, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hyperion Financial Reporting accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hyperion Financial Reporting. CVSS 3.1 Base Score 8.5 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L).

### Impact A carefully crafted malicious OpenRefine project tar file can be used to trigger arbitrary code execution if a user can be convinced to import it. ### Patches The vulnerability exists in all versions of OpenRefine up to and including 3.7.3. Users should update to OpenRefine 3.7.4 as soon as possible. ### Workarounds Only import OpenRefine projects from trusted sources. ### References A similar [issue](https://github.com/OpenRefine/OpenRefine/issues/1840) existed in the Create Project feature ([CVE-2018-19859](https://nvd.nist.gov/vuln/detail/CVE-2018-19859)), which was fixed by PR [#1901](https://github.com/OpenRefine/OpenRefine/pull/1901).
