Description

This security bulletin contains information about 5 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2019-5258)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to cause the affected board abnormal.

The vulnerability exists due to a boundary error when processing a crafted message. A local attacker who logs in to the board can send specially crafted messages from the internal network port or tamper with inter-process message packets, trigger memory corruption and cause the affected board abnormal.



2) Resource management error (CVE-ID: CVE-2019-5257)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to improper management of system resources. A local attacker who logs in to the board can send specially crafted messages from the internal network port or tamper with inter-process message packets and cause a denial of service condition on the target system.


3) NULL pointer dereference (CVE-ID: CVE-2019-5256)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to a NULL pointer dereference error. A local attacker can send specially crafted parameters, cause a denial of service condition and the process reboot.


4) Out-of-bounds read (CVE-ID: CVE-2019-5255)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/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 insufficient validation of the message. A remote attacker can send specially crafted messages from a FTP client, trigger out-of-bounds read error and cause a denial of service condition on the target device.


5) Out-of-bounds read (CVE-ID: CVE-2019-5254)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to cause the affected board abnormal.

The vulnerability exists due to insufficient validation of the message. A local attacker who logs in to the board can send specially crafted messages from the internal network port or tamper with inter-process message packets, trigger out-of-bounds read error and cause the affected board abnormal.
