Description

This security bulletin contains information about 6 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2020-1836)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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


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

The vulnerability exists due to excessive data output by the application in certain function's default configuration. A remote attacker on the local network can launch the attack via a crafted WI-FI hotspot and gain unauthorized access to sensitive information on the system.


2) Information disclosure (CVE-ID: CVE-2020-9077)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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


The vulnerability allows a local attacker to gain access to potentially sensitive information.

The vulnerability exists due to the affected system does not properly authenticate the application that access a specified interface. A local attacker can trick a victim to install a malicious software and gain unauthorized access to sensitive information on the system.


3) Memory leak (CVE-ID: CVE-2020-9249)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

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


The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak. A remote attacker on the local network can send a specially crafted messages, force the application to leak memory and perform denial of service attack.


4) Improper Authorization (CVE-ID: CVE-2020-9245)

CWE-ID: CWE-285 - Improper Authorization

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 bypass authorization checks.

The vulnerability exists due to improper authorization. A local attacker can trick a victim to install a malicious application and cause a denial of service condition of PHONE function.


5) Integer overflow (CVE-ID: CVE-2020-9095)

CWE-ID: CWE-190 - Integer overflow

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 integer overflow. A local attacker can send malicious message, trigger integer overflow and cause a denial of service condition on the target system.


6) Out-of-bounds read (CVE-ID: CVE-2020-9096)

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

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


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

The vulnerability exists due to a boundary condition when processing some messages sent from other module. A local user can send a malicious message, trigger out-of-bounds read error and cause a denial of service condition on the system.
