CVSS Base Score: 5.6 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/152081 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L) CVEID: CVE-2018-12549 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-12549 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-12549 DESCRIPTION: Eclipse OpenJ9 could allow a remote attacker to execute arbitrary code on the system, caused by the failure to omit a null check on the receiver object of an Unsafe call when accelerating it. An attacker could exploit this vulnerability to execute arbitrary code on the system. CVSS Base Score: 9.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/157513 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2018-12547 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-12547 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-12547 DESCRIPTION: Eclipse OpenJ9 is vulnerable to a buffer overflow, caused by improper bounds checking by the jio_snprintf() and jio_vsnprintf() functions. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash. CVSS Base Score: 9.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/157512 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2019-2422 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-2422 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-2422 DESCRIPTION: An unspecified vulnerability in Oracle Java SE related to the Java SE Libraries component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors. CVSS Base Score: 3.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/155741 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N) CVEID: CVE-2019-2449 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-2449 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-2449 DESCRIPTION: An unspecified vulnerability in Oracle Java SE related to the Java SE Deployment component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors. CVSS Base Score: 3.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/155766 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L) CVEID: CVE-2019-2426 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-2426 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-2426 DESCRIPTION: An unspecified vulnerability in Oracle Java SE related to the Java SE Networking component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/155744 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2018-11212 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-11212 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-11212 DESCRIPTION: libjpeg is vulnerable to a denial of service, caused by divide-by-zero error in the alloc_sarray function in jmemmgr.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash. CVSS Base Score: 3.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/143429 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L) AFFECTED PRODUCTS AND VERSIONS: AIX 7.1, 7.2 VIOS 2.2.x The following fileset levels (VRMF) are vulnerable, if the respective Java version is installed: For Java7: Less than 7.0.0.640 For Java7.1: Less than 7.1.0.440 For Java8: Less than 8.0.0.530 Note: To find out whether the affected Java filesets are installed on your systems, refer to the lslpp command found in AIX user's guide. Example: lslpp -L | grep -i java REMEDIATION: Note: Recommended remediation is to always install the most recent Java package available for the respective Java version.
