IBM® Db2® is vulnerable to a denial of service when fetching from certain tables under specific configurations

IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.3 for Linux, UNIX and Windows (includes Db2 Connect Server) could allow an authenticated user to cause a denial of service due to improper neutralization of special elements in data query logic when certain configurations exist.

IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.3 for Linux, UNIX and Windows (includes DB2 Connect Server) could allow an authenticated user to cause a denial of service using a specially crafted SQL query due to improper allocation of system resources.

IBM® Db2® is vulnerable to a trap or return SQLCODE -901 when compiling a specially crafted query with a defined index

IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.4 for Linux, UNIX and Windows (includes Db2 Connect Server) could allow an authenticated user to cause a denial of service due to improper neutralization of special elements in data query logic.

Stack-based buffer overflow in db2dasrrm in the DB2 Administration Server (DAS) in IBM DB2 Universal Database 9.5 before Fix Pack 1, 9.1 before Fix Pack 4a, and 8 before FixPak 16 allows local users to execute arbitrary code via a long DASPROF environment variable.

Untrusted search path vulnerability in db2pd in IBM DB2 Universal Database (UDB) 8 before FixPak 16 and 9 before Fix Pack 4 allows local users to gain root privileges via a modified DB2INSTANCE environment variable that points to a malicious library. NOTE: this might be the same issue as CVE-2008-0697.

db2dasrrm in the DB2 Administration Server (DAS) in IBM DB2 Universal Database 9.5 before Fix Pack 1, 9.1 before Fix Pack 4a, and 8 before FixPak 16 allows local users to overwrite arbitrary files via a symlink attack on files used for initialization.

IBM DB2 UDB 9.1 before Fixpak 4 does not properly manage storage of a list containing authentication information, which might allow attackers to cause a denial of service (instance crash) or trigger memory corruption. NOTE: the vendor description of this issue is too vague to be certain that it is security-related.

Unspecified vulnerability in IBM Rational ClearQuest (CQ), when a Microsoft SQL Server or an IBM DB2 database is used, allows attackers to corrupt data via unspecified vectors.

Stack-based buffer overflow in the AUTH_LIST_GROUPS_FOR_AUTHID function in IBM DB2 UDB 9.1 before Fixpak 3 allows attackers to cause a denial of service and possibly execute arbitrary code via a long argument.

IBM DB2 UDB 8 before Fixpak 15 does not properly check authorization, which allows remote authenticated users with a certain SELECT privilege to have an unknown impact via unspecified vectors. NOTE: this issue is probably related to CVE-2007-1089, but this is uncertain due to lack of details.

IBM DB2 UDB 8 before Fixpak 15 and 9.1 before Fixpak 3 does not properly revoke privileges on methods, which allows remote authenticated users to execute a method after revocation until the routine auth cache is flushed.

Stack-based buffer overflow in IBM DB2 UDB 8 before Fixpak 15 and 9.1 before Fixpak 3 allows attackers to execute arbitrary code via a long DASPROF and possibly other environment variables, which are copied into the buildDasPaths buffer.

Multiple untrusted search path vulnerabilities in IBM DB2 UDB 8 before Fixpak 15 and 9.1 before Fixpak 3 allow local users to gain privileges via certain vectors related to (1) DB2 instance or FMP startup on Linux and Solaris; (2) exec of executables while running as root on non-Windows systems, as demonstrated by AIX; and unspecified vectors involving (3) db2licm and (4) db2pd.

IBM DB2 UDB 8 before Fixpak 15 and 9.1 before Fixpak 3 allows local users to create arbitrary directories and execute arbitrary code via a "crafted localized message file" that enables a format string attack, possibly involving the (1) OSSEMEMDBG or (2) TRC_LOG_FILE environment variable in db2licd (db2licm).

Multiple vulnerabilities in IBM DB2 UDB 8 before Fixpak 15 and 9.1 before Fixpak 3 allow local users to create arbitrary files via (1) unspecified vectors where an attacker's umask is honored, (2) /etc/ld.so.preload, (3) certain "cron data file locations", and other unspecified vectors possibly involving the (4) OSSEMEMDBG or (5) TRC_LOG_FILE environment variable in db2licd (db2licm).

Directory traversal vulnerability in IBM DB2 UDB 8 before Fixpak 15 and 9.1 before Fixpak 3 allows local users to create arbitrary files via a .. (dot dot) in an unspecified environment variable, which is appended to "/tmp/" and used as a log file. NOTE: this issue might be related to symlink following.

Unspecified vulnerability in the eClient in IBM DB2 Content Manager 8.4.1 before 8.4.1.1 has unknown impact and attack vectors.

Multiple race conditions in IBM DB2 UDB 8 before Fixpak 15 and 9.1 before Fixpak 3 allow local users to gain root privileges via a symlink attack on certain files.

Unspecified vulnerability in the server in IBM DB2 8 before FP17a, 9.1 before FP6a, and 9.5 before FP3a allows remote authenticated users to cause a denial of service (trap) via a crafted data stream.

Unspecified vulnerability in IBM DB2 8 before FP17a, 9.1 before FP6a, and 9.5 before FP3a allows remote attackers to cause a denial of service (infinite loop) via a crafted CONNECT data stream.
