IBM MQ Appliance affected by NSS and libgcrypt vulnerabilities (CVE-2018-12404
and CVE-2018-0495)
Security Bulletin
Summary
IBM MQ Appliance has resolved the following NSS and libgcrypt vulnerabilities.
Vulnerability Details
CVEID: CVE-2018-12404
DESCRIPTION: A cached side channel attack during handshakes using RSA
encryption could allow for the decryption of encrypted content. This is a
variant of the Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack)
and affects all NSS versions prior to NSS 3.41.
CVSS Base score: 5.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
155087 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2018-0495
DESCRIPTION: Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a
memory-cache side-channel attack on ECDSA signatures that can be mitigated
through the use of blinding during the signing process in the
_gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the
Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs
access to either the local machine or a different virtual machine on the same
physical host.
CVSS Base score: 5.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
144828 for the current score.
