Untrusted search path vulnerability in IBM InfoSphere BigInsights 3.0, 3.0.0.1, 3.0.0.2, and 4.0, when a DB2 database is used, allows local users to gain privileges via a Trojan horse library that is loaded by a setuid or setgid program.

Versions of IBM DB2 10.5 earlier than Fix Pack 7 are potentially affected by multiple vulnerabilities :

 - A flaw exists that is due to the program setting insecure permissions for the Self Tuning Memory Manager (STMM) log file.  This may allow a local attacker to read or write to log files.
 - A flaw exists related to the improper building of binaries.  This may allow a local attacker plant a malicious library in a specific location to gain elevated privileges.
 - A flaw exists in multiple methods that is triggered during the handling of queries.  This may allow an authenticated attacker to crash the database.

According to its version, the installation of IBM DB2 10.5 running on the remote host is prior to Fix Pack 7. It is, therefore, affected by the following vulnerabilities :

  - A security feature bypass vulnerability, known as FREAK     (Factoring attack on RSA-EXPORT Keys), exists due to the     support of weak EXPORT_RSA cipher suites with keys less     than or equal to 512 bits. A man-in-the-middle attacker     may be able to downgrade the SSL/TLS connection to use     EXPORT_RSA cipher suites which can be factored in a     short amount of time, allowing the attacker to intercept     and decrypt the traffic. (CVE-2015-0204)

  - A denial of service vulnerability exists when processing     an ECParameters structure due to an infinite loop that     occurs when a specified curve is over a malformed binary     polynomial field. A remote attacker can exploit this to     perform a denial of service against any system that     processes public keys, certificate requests, or     certificates. This includes TLS clients and TLS servers     with client authentication enabled. (CVE-2015-1788)

  - A privilege escalation vulnerability exists due to an     untrusted search path flaw. A local attacker can exploit     this, via a specially crafted library that is loaded by     a setuid or setgid process, to gain elevated privileges     on the system. (CVE-2015-1947)

  - A security feature bypass vulnerability exists, known as     Bar Mitzvah, due to improper combination of state data     with key data by the RC4 cipher algorithm during the     initialization phase. A man-in-the-middle attacker can     exploit this, via a brute-force attack using LSB values,     to decrypt the traffic. (CVE-2015-2808)

  - A man-in-the-middle vulnerability, known as Logjam,     exists due to a flaw in the SSL/TLS protocol. A remote     attacker can exploit this flaw to downgrade connections     using ephemeral Diffie-Hellman key exchange to 512-bit     export-grade cryptography. (CVE-2015-4000)

Note that several of these vulnerabilities are due to the bundled GSKit component and the embedded FCM 4.1 libraries.
