Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2 and 12.2.0.1. Difficult to exploit vulnerability allows low privileged attacker having Create Session, Create Procedure privilege with network access via multiple protocols to compromise Java VM. While the vulnerability is in Java VM, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java VM. CVSS 3.0 Base Score 8.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H).

A deserialization flaw was discovered in the jackson-databind in versions before 2.8.10 and 2.9.1, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaw CVE-2017-7525 by blacklisting more classes that could be used maliciously.

Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2 and 12.2.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java VM. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java VM, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java VM. CVSS 3.0 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).

Vulnerability in the Core RDBMS component of Oracle Database Server. Supported versions that are affected are 12.1.0.2 and 12.2.0.1. Easily exploitable vulnerability allows high privileged attacker having Create Session, Execute Catalog Role privilege with network access via Oracle Net to compromise Core RDBMS. While the vulnerability is in Core RDBMS, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Core RDBMS. CVSS 3.0 Base Score 9.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).

Vulnerability in the Core RDBMS component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2, and 12.2.0.1. Difficult to exploit vulnerability allows high privileged attacker having Local Logon privilege with network access via multiple protocols to compromise Core RDBMS. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Core RDBMS accessible data. Note: Applicable only to Windows platform. CVSS 3.0 Base Score 2.0 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:N/A:N).

A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients.

Perl might allow context-dependent attackers to bypass the taint protection mechanism in a child process via duplicate environment variables in envp.
