Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Improper Null Termination (CVE-ID: CVE-2020-11908)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to improper null termination in DHCP component. A remote attacker on the local network can send a specially crafted packet and gain unauthorized access to sensitive information on the system.
2) Input validation error (CVE-ID: CVE-2020-11914)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied input in ARP component. A remote attacker on the local network can send a specially crafted packet, trigger out-of-bounds read and read contents of memory on the system.
3) Input validation error (CVE-ID: CVE-2020-11912)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in TCP component. A remote attacker on the local network can send a specially crafted packet, trigger out-of-bounds read and cause a denial of service condition on the target system.
4) Improper access control (CVE-ID: CVE-2020-11911)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions. A remote attacker can bypass implemented security restrictions and change one specific configuration value.
5) Input validation error (CVE-ID: CVE-2020-11910)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied input in ICMPv4 component . A remote attacker can send a specially crafted packet, trigger out-of-bounds read and read contents of memory on the system.
6) Information disclosure (CVE-ID: CVE-2020-11909)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to improper input validation in IPv4 component. A remote attacker can send a specially crafted packet and gain unauthorized access to sensitive information on the system.
7) Improper Handling of Length Parameter Inconsistency (CVE-ID: CVE-2020-11907)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to improper handling of length parameter inconsistency in TCP component. A remote attacker on the local network can send a specially crafted packet and execute arbitrary code on the target system.
8) Input validation error (CVE-ID: CVE-2020-11906)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input in ethernet link layer component. A remote attacker on the local network can send a specially crafted packet and execute arbitrary code on the system.
9) Integer overflow (CVE-ID: CVE-2020-11904)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in memory allocation component. A remote attacker can send a specially crafted packet, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Out-of-bounds read (CVE-ID: CVE-2020-11903)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in DHCP component. A remote attacker on the local network can send a specially crafted packet, trigger out-of-bounds read error and read contents of memory on the system.
11) Input validation error (CVE-ID: CVE-2020-11901)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to insufficient validation of user-supplied input in DNS resolver component. A remote attacker can send a specially crafted packet and execute arbitrary code on the target system.
12) Expected behavior violation (CVE-ID: CVE-2019-12264)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a logical flaw within the ipdhcpc DHCP client when processing broadcasted IP addresses. A remote attacker with control over DHCP server within the local network segment can assign multicast or broadcast addresses to the victim.
