Security Bulletin
Summary
OpenSSL has a security vulnerability that allows a remote attacker to exploit the application. OpenSSL is used by Rational BuildForge Agent shipped with IBM Rational Team Concert. Rational BuildForge has addressed the applicable CVE.
Vulnerability Details
CVEID: CVE-2019-1547
DESCRIPTION: OpenSSL could allow a local authenticated attacker to obtain sensitive information, caused by the ability to construct an EC group missing the cofactor using explicit parameters instead of using a named curve. An attacker could exploit this vulnerability to obtain full key recovery during an ECDSA signature operation.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/167020 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2019-1549
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by the failure to include protection in the event of a fork() system call to ensure that the parent and child processes do not share the same RNG state. An attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/167021 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2019-1563
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a padding oracle attack in PKCS7_dataDecode and CMS_decrypt_set1_pkey. By sending an overly large
number of messages to be decrypted, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/167022 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
