Security Bulletin

Summary

OpenSSL vulnerabilities were disclosed by the OpenSSL Project. OpenSSL
is used by Rational BuildForge Agent shipped with IBM Rational Team
Concert. Rational BuildForge has addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2018-0739
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending
specially crafted ASN.1 data with a recursive definition, a remote attacker
could exploit this vulnerability to consume excessive stack memory.
CVSS Base Score : 5.3
CVSS Temporal Score : See
https://exchange.xforce.ibmcloud.com/vulnerabilities/140847 for the current score.
CVSS Environmental Score* : Undefined
CVSS Vector : (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

CVEID: CVE-2017-3738
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an overflow bug in the AVX2 Montgomery multiplication
procedure used in exponentiation with 1024-bit moduli. An attacker could
exploit this vulnerability to obtain information about the private key. Note:
In order to exploit this vulnerability, the server would have to share the
DH1024 private key among multiple clients, which is no longer an option
since CVE-2016-0701.
CVSS Base Score: 3.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/136078 for the current score.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2017-3737
DESCRIPTION: An unspecified vulnerability in multiple Oracle products could
allow an unauthenticated attacker to cause low confidentiality impact,
low integrity impact, and high availability impact.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/136077 for the current score.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
