There are multiple vulnerabilities in IBM Runtime Environment Java Versions 7
and 8, which are used by IBM Rational DOORS Web Access. IBM Rational DOORS Web
Access has addressed the applicable CVEs. 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)

Affected Products and Versions

IBM Rational DOORS Web Access: 9.5.1 - 9.5.1.10
IBM Rational DOORS Web Access: 9.5.2 - 9.5.2.9
