Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Improper access control (CVE-ID: CVE-2019-0150)
The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in firmware. A local user can bypass implemented security restrictions and cause a denial of service (DoS) on the target system.
2) Resource exhaustion (CVE-ID: CVE-2019-0148)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a resource leak in i40e driver. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Input validation error (CVE-ID: CVE-2019-0147)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in i40e driver. A local user can cause a denial of service condition on the target system.
4) Buffer overflow (CVE-ID: CVE-2019-0145)
The vulnerability allows a local user to escalate privileges on the target system.
The vulnerability exists due to a boundary error in i40e driver. A local user can trigger memory corruption and escalate privileges on the target system.
5) Improper Handling of Exceptional Conditions (CVE-ID: CVE-2019-0144)
The vulnerability allows a local user to perform a denial of service (DoS) attack on the target system.
The vulnerability exists due to the affected software does not handle or incorrectly handles an exceptional condition in firmware. A local user can cause a denial of service condition on the target system.6) Improper Handling of Exceptional Conditions (CVE-ID: CVE-2019-0143)
The vulnerability allows a local user to perform a denial of service (DoS) attack on the target system.
The vulnerability exists due to the affected software does not handle or incorrectly handles an exceptional condition in Kernel-mode driver. A local user can cause a denial of service condition on the target system.
7) Buffer overflow (CVE-ID: CVE-2019-0140)
The vulnerability allows a remote attacker to escalate privileges on the target system.
The vulnerability exists due to a boundary error in firmware. An attacker on adjacent network can trigger memory corruption and escalate privileges on the target system.
8) Improper access control (CVE-ID: CVE-2019-0139)
The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions. A local user can bypass implemented security restrictions and enable an escalation of privilege, denial of service or information disclosure.
