Security Bulletin: Vulnerabilities in OpenSSL affect IBM MessageSight
More support for:
OpenSSL vulnerabilities were disclosed by the OpenSSL Project. OpenSSL is
used by IBM MessageSight. IBM MessageSight has addressed the applicable CVEs.
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
failure to properly handle attempts to use unsupported protocols by the
ssl23_get_client_hello function in s23_srvr.c. A remote attacker could
exploit this vulnerability using an unexpected handshake to trigger a NULL
pointer dereference and cause the daemon to crash.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99706 for the
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
DESCRIPTION: OpenSSL could allow a remote authenticated attacker to bypass
security restrictions, caused by the acceptance of a DH certificate for
client authentication without verification. An attacker could exploit this
vulnerability to authenticate without the use of a private key.
CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99708 for the
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:S/C:N/I:P/A:N)
