Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Use of Uninitialized Variable (CVE-ID: CVE-2025-2520)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to use of uninitialized variable in the common Epic Platform Analyzer (EPA) communications. A remote attacker can cause a denial of service condition on the target system.


2) Buffer overflow (CVE-ID: CVE-2025-2521)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the component Control Data Access (CDA). A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Sensitive Information in Resource Not Removed Before Reuse (CVE-ID: CVE-2025-2522)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to sensitive information in resource not removed in the component Control Data Access (CDA). A remote attacker can gain access to sensitive information on the system, leading to communication channel manipulation.


4) Integer underflow (CVE-ID: CVE-2025-2523)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer underflow in the component Control Data Access (CDA). A remote attacker can trigger integer underflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


5) Integer underflow (CVE-ID: CVE-2025-3946)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer underflow in the component Control Data Access (CDA). A remote attacker can trigger integer underflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


6) Integer underflow (CVE-ID: CVE-2025-3947)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer underflow in the component Control Data Access (CDA). A remote attacker can trigger integer underflow and cause a denial of service condition on the target system.
