Security Bulletin: Multiple Vulnerabilities in IBM Java Runtime Affect IBM
Sterling Secure Proxy
Document information
More support for: Sterling Secure Proxy
Software version: 3.4.2.0, 3.4.3.2, 6.0.0.0
Operating system(s): AIX, Linux, Windows
Reference #: 0885937
Modified date: 28 May 2019
Summary
There are multiple vulnerabilities in IBM(R) Runtime Environment Java(TM) Version
1.8
used by IBM Sterling Secure Proxy. These issues were disclosed as part of the
IBM Java SDK updates in January 2019.
Vulnerability Details
CVEID: 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 more information
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-2018-1890
DESCRIPTION: IBM SDK, Java Technology Edition Version 8 on the AIX platform
uses absolute RPATHs which may facilitate code injection and privilege
elevation by local users.
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-2019-2426
DESCRIPTION: An unspecified vulnerability 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
