Vulnerability Details
CVEID: CVE-2019-4057
DESCRIPTION: IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) could allow malicious user with access to the DB2 instance account to leverage a fenced execution process to execute arbitrary code as root.
CVSS Base Score: 6.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/156567 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2019-4101
DESCRIPTION: DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) is vulnerable to a denial of service. Users that have both EXECUTE on PD_GET_DIAG_HIST and access to the diagnostic directory on the DB2 server can cause the instance to crash.
CVSS Base Score: 6.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/158091 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-4102
DESCRIPTION: IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/158092 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2019-4154
DESCRIPTION: IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) is vulnerable to a buffer overflow, which could allow an authenticated local attacker to execute arbitrary code on the system as root.
CVSS Base Score: 8.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/158519 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2019-4386
DESCRIPTION: IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) could allow an authenticated user to execute a function that would cause the server to crash.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/162174 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-4322
DESCRIPTION: IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) is vulnerable to a buffer overflow, which could allow an authenticated local attacker to execute arbitrary code on the system as root.
CVSS Base Score: 8.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/161202 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
Security Bulletin: IBM Db2 is vulnerable to denial of service (CVE-2019-4386).
Security Bulletin: IBM Db2 is vulnerable to buffer overflow leading to potential arbitrary code execution as root (CVE-2019-4154).
Security Bulletin: IBM Db2 does not explicitly forbid a weaker than expected 3DES cipher when configured to use SSL (CVE-2019-4102).
Security Bulletin: Under specialized conditions, IBM Db2 is vulnerable to denial of service (CVE-2019-4101).
Security Bulletin: IBM Db2 is vulnerable to privilege escalation to root via malicious use of fenced user (CVE-2019-4057).
