EMC Documentum Content Server Multiple Vulnerabilities (ESA-2014-079)

Synopsis :

The remote host is affected by multiple vulnerabilities.

Description :

The remote host is running a version of EMC Documentum Content Server
that is affected by multiple vulnerabilities :

- An error exists in the 'ssl3_read_bytes' function
that permits data to be injected into other sessions
or allows denial of service attacks. Note that this
issue is exploitable only if SSL_MODE_RELEASE_BUFFERS
is enabled. (CVE-2010-5298)

- An error exists related to the implementation of the
Elliptic Curve Digital Signature Algorithm (ECDSA) that
could allow nonce disclosure via the 'FLUSH+RELOAD'
cache side-channel attack. (CVE-2014-0076)

- A buffer overflow error exists related to invalid DTLS
fragment handling that permits the execution of
arbitrary code or allows denial of service attacks.
Note that this issue only affects OpenSSL when used
as a DTLS client or server. (CVE-2014-0195)

- An error exists in the 'do_ssl3_write' function that
permits a NULL pointer to be dereferenced, which could
allow denial of service attacks. Note that this issue
is exploitable only if SSL_MODE_RELEASE_BUFFERS is
enabled. (CVE-2014-0198)

- An error exists related to DTLS handshake handling that
could allow denial of service attacks. Note that this
issue only affects OpenSSL when used as a DTLS client.
(CVE-2014-0221)

- An error exists in the processing of ChangeCipherSpec
messages that allows the usage of weak keying material.
This permits simplified man-in-the-middle attacks to be
done. (CVE-2014-0224)

- A remote code execution vulnerability exists due to
improper authorization checks. A remote, authenticated
attacker can exploit this vulnerability to execute
arbitrary code. (CVE-2014-4618)

- An information disclosure vulnerability exists due to a
flaw in the Documentum Query Language (DQL) engine. A
remote, authenticated attacker can exploit this
vulnerability to conduct DQL injection attacks and
read arbitrary data from the database. Note that this
only affects Content Server installations running on
Oracle Database. (CVE-2014-2520)

- An error exists in the 'dtls1_get_message_fragment'
function related to anonymous ECDH cipher suites. This
could allow denial of service attacks. Note that this
issue only affects OpenSSL TLS clients. (CVE-2014-3470)

- An information disclosure vulnerability exists due to
improper authorization checks on certain RPC commands.
A remote, authenticated attacker can exploit this
vulnerability to retrieve meta-data of unauthorized
system objects. (CVE-2014-2521)
