Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2020-2773)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the Security component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
2) Missing Encryption of Sensitive Data (CVE-ID: CVE-2020-14781)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the JNDI component in Java SE Embedded when processing encrypted LDAP requests. A remote non-authenticated attacker can downgrade the encrypted LDAP connection and gain access to sensitive information.
3) Improper input validation (CVE-ID: CVE-2020-14782)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to an error in CertPath implementation within the Libraries component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
4) Improper input validation (CVE-ID: CVE-2020-14803)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Libraries component in Java SE. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
5) Stack-based buffer overflow (CVE-ID: CVE-2020-27221)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when the virtual machine or JNI natives are converting from UTF-8 characters to platform encoding. A remote unauthenticated attacker can trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
