Untrusted search path vulnerability in IBM DB2 9.7 through FP11, 10.1 through FP5, 10.5 before FP8, and 11.1 GA on Linux, AIX, and HP-UX allows local users to gain privileges via a Trojan horse library that is accessed by a setuid or setgid program.

According to its version, the installation of IBM DB2 10.5 running on the remote host is prior to Fix Pack 8. It is, therefore, affected by the following vulnerabilities :

  - A local privilege escalation vulnerability exists due to     insecurely loading binaries planted in a location that a     SETGID or SETUID binary would execute. A local attacker     can exploit this, via a malicious binary, to gain root     privileges. (CVE-2016-5995)

  - A denial of service vulnerability exists in the     SQLNP_SCOPE_TRIAL() function due to improper handling of     SQL statements. An authenticated, remote attacker can     exploit this to crash the database.

  - A denial of service vulnerability exists in the Query     Compiler QGM due to improper handling of specific     queries. An authenticated, remote attacker can exploit     this, via a specially crafted query, to crash the     database.

Versions of IBM DB2 10.5 prior to Fix Pack 8 and 11.x prior to 11.1 are potentially affected by multiple vulnerabilities :

 - An unspecified flaw exists that may allow a local attacker to gain elevated privileges. No further details have been provided by the vendor.
 - An unspecified flaw exists that may allow a local attacker to gain access to arbitrary memory locations. No further details have been provided by the vendor.
 - An unspecified flaw exists that is triggered when dereferencing user pointers. This may allow a local attacker to crash the file system.
 - A flaw exists in the 'DTDScanner::scanChildren()' function in 'validators/DTD/DTDScanner.cpp' that is triggered when handling user requests. With a specially crafted request, a context-dependent attacker can cause the application linked against the library to exhaust resources causing it to stop responding or crash.
 - A flaw exists that is triggered when a local attacker sets environment variables that are processed by setuid programs. This may allow the attacker to execute commands with root privileges.
 - A flaw exists that is triggered when a local attacker supplies command line parameters to setuid programs. This may allow the attacker to execute commands with root privileges.
 - An overflow condition exists that is triggered as certain input is not properly validated. This may allow an authenticated remote attacker to cause a buffer overflow, potentially allowing them to bypass security restrictions and disclose sensitive information.
 - A flaw exists that is due to the program insecurely loading binaries planted in a location that a SETGID or SETUID binary would execute. This may allow a local attacker to gain elevated, root privileges.
 - A flaw exists in the 'SQLNP_SCOPE_TRIAL()' function that is triggered during the handling of SQL statements. This may allow an authenticated attacker to crash the database.
 - Multiple flaws exist in the Query Compiler QGM that is triggered when handling specific queries. With a specially crafted query, an authenticated attacker can cause the database to crash.

Versions of IBM DB2 9.7 prior to Fix Pack 11 are potentially affected by multiple vulnerabilities :

 - A flaw exists in the query compiler QGM that is triggered when handling duplicate reloc entry queries. This may allow an authenticated attacker to crash the database.
 - A flaw exists in the 'SQLEX_FIND_GROUP()' function that is triggered during the handling of group name results. This may allow an authenticated attacker to crash the database.
 - A flaw exists in the Query Compiler QGM that is triggered during the handling of 'DBCLOB' column types. This may allow an authenticated attacker to crash the database.
 - A flaw exists in the 'SQLRA_GET_SECT_INFO_BY_CURSOR_NAME()' function in 'Relational Data Services' that is triggered during the handling of stored procedures. This may allow an authenticated attacker to crash the database.
 - A flaw exists that is due to the program insecurely loading binaries planted in a location that a SETGID or SETUID binary would execute. This may allow a local attacker to gain elevated, root privileges.

Versions of IBM DB2 10.1 earlier than Fix Pack 5 are potentially affected by multiple vulnerabilities :

 - An unspecified flaw exists in the monitoring or audit facility due to passwords being stored when handling specially crafted commands.  A remote, authenticated attacker can exploit this to access sensitive information. (CVE-2014-0919)
 - A stack-based buffer overflow condition exists due to improper validation of user-supplied input when handling crafted 'ALTER MODULE' statements.  A remote, authenticated attacker can exploit this to cause a denial of service or execute arbitrary code. (CVE-2014-3094)
 - A flaw exists when handling a crafted 'UNION' clause in a subquery of a 'SELECT' statement.  A remote, authenticated attacker can exploit this to cause a denial of service. (CVE-2014-3095)
 - A denial of service vulnerability exists when immediate 'AUTO_REVAL' is enabled.  A remote, authenticated attacker can exploit this, via a crafted 'ALTER TABLE' statement, to crash the server. (CVE-2014-6159)
 - A denial of service vulnerability exists when handling an identity column within a crafted 'ALTER TABLE' statement.  A remote, authenticated attacker can exploit this vulnerability to crash the server. (CVE-2014-6209)
 - A denial of service vulnerability exists when handling multiple 'ALTER TABLE' statements specifying the same column.  A remote, authenticated attacker can exploit this vulnerability to crash the server. (CVE-2014-6210)
 - A flaw exists that is triggered when handling specially crafted XML queries.  A remote, authenticated attacker can exploit this to cause a consumption of resources, resulting in a denial of service. (CVE-2014-8901)
 - 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.
 - A double-free flaw exists in the CLI application.  The issue is triggered as user-supplied input is not properly validated when handling client disconnects.  This may allow a remote attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code.
 - A flaw exists that is triggered when handling 'SUM' or 'GROUP' BY queries with a 'SUBSELECT' that contains unnest.  This may allow an attacker to cause the database to crash.
 - An unspecified flaw exists in the 'sqldRemoveCachedTableEntry()' function that may allow an authenticated attacker to cause a DB2 instance to crash.
 - A flaw exists that is triggered as user-supplied input is not properly validated when handling Partial Aggregation operators (PED, PEA).  This may allow an authenticated attacker to corrupt memory and cause a denial of service.
 - A flaw exists that is due to the program setting insecure 666 permissions for log files.  This may allow a local attacker to manipulate logs.
 - A flaw exists in the 'sqlex_find_group()' function in the handling of group names.  This issue is triggered when returning a cumulative group name length greater than 64k for a user id.  This may allow an authenticated attacker to crash the server.
 - A flaw exists in the 'sqlsBinSortPopulateRecPointers()' function.  The issue is triggered as user-supplied input is not properly validated when performing resettable sorts.  This may allow an authenticated attacker to corrupt memory and cause a denial of service.
 - A flaw exists that is triggered when handling generated tables with 'INSERT INTO' statements.  This may allow an authenticated attacker to cause DB2 to crash.
 - A flaw exists that is triggered when invoking runstats against a user temporary table while the index clause explicitly specifies index names while omitting the index scheme name.  This may allow an authenticated attacker to cause a crash.
 - A flaw exists in the DRDA communication protocol that is triggered during the handling of messages.  This may allow an authenticated remote attacker to trigger a large memory overwrite.
 - A flaw exists that is due to the program insecurely loading binaries planted in a location that a SETGID or SETUID binary would execute. This may allow a local attacker to gain elevated, root privileges.
