IBM DB2 10.5 < Fix Pack 6 Multiple Vulnerabilities (Bar Mitzvah)
Critical Nessus Network Monitor Plugin ID 9198
SynopsisThe remote IBM DB2 database server is vulnerable to multiple attack vectors.
DescriptionVersions of IBM DB2 10.5 earlier than Fix Pack 6 are potentially affected by multiple vulnerabilities :
- An unspecified flaw exists in IBM DB2 XML Native Encryption that may allow an attacker to gain access to private memory information. No further details have been provided. (OSVDB 127288)
- A flaw exists in the IBM Global Security Kit (GSKit) when handling RSA temporary keys in a non-export RSA key exchange ciphersuite. A man-in-the-middle attacker can exploit this to downgrade the session security to use weaker EXPORT_RSA ciphers, thus allowing the attacker to more easily monitor or tamper with the encrypted stream. (CVE-2015-0138)
- An unspecified flaw in the General Parallel File System (GPFS) allows a local attacker to gain root privileges. (CVE-2015-0197)
- A flaw exists in the General Parallel File System (GPFS), related to certain cipherList configurations, that allows a remote attacker, using specially crafted data, to bypass authentication and execute arbitrary programs with root privileges. (CVE-2015-0198)
- A denial of service vulnerability exists in the General Parallel File System (GPFS) that allows a local attacker to corrupt kernel memory by sending crafted ioctl character device calls to the mmfslinux kernel module. (CVE-2015-0199)
- 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)
- An information disclosure vulnerability exists due to improper block cipher padding by TLSv1 when using Cipher Block Chaining (CBC) mode. A remote attacker, via an 'Oracle Padding' side channel attack, can exploit this vulnerability to gain access to sensitive information. Note that this is a variation of the POODLE attack.
