Description
This security bulletin contains information about 6 vulnerabilities.
1) Use of Uninitialized Variable (CVE-ID: CVE-2025-2520)
CWE-ID: CWE-457 - Use of Uninitialized Variable
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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)
CWE-ID: CWE-226 - Sensitive Information in Resource Not Removed Before Reuse
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
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)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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.
