IIBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.5 could allow an authenticated user with CONNECT privileges to cause a denial of service using a specially crafted query. IBM X-Force ID: 270264.

IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.5 is vulnerable to an insecure cryptographic algorithm and to information disclosure in stack trace under exceptional conditions. IBM X-Force ID: 270730.

IBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) 11.5 under certain circumstances could allow an authenticated user to the database to cause a denial of service when a statement is run on columnar tables. IBM X-Force ID: 273393.

IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.5 federated server is vulnerable to a denial of service when a specially crafted cursor is used. IBM X-Force ID: 268759.

IBM DB2 for Linux, UNIX and Windows (includes Db2 Connect Server) 10.5, 11.1, and 11.5 is vulnerable to denial of service with a specially crafted RUNSTATS command on an 8TB table. IBM X-Force ID: 264809.

Directory traversal vulnerability in the UTL_FILE module in IBM DB2 and DB2 Connect 10.1 before FP1 on Windows allows remote authenticated users to modify, delete, or read arbitrary files via a pathname in the file field.

Unspecified vulnerability in IBM DB2 9.7 before FP5 on UNIX, when the Self Tuning Memory Manager (STMM) feature and the AUTOMATIC DATABASE_MEMORY setting are configured, allows local users to cause a denial of service (daemon crash) via unknown vectors.

IBM DB2 UDB 8 before Fixpak 17 allows remote attackers to cause a denial of service (instance crash) via a crafted CONNECT/ATTACH data stream that simulates a V7 client connect/attach request. NOTE: this may overlap CVE-2008-3858. NOTE: this issue exists because of an incomplete fix for CVE-2008-3959.

Unspecified vulnerability in the ADMIN_SP_C2 procedure in IBM DB2 8 before FP16, 9.1 before FP4a, and 9.5 before FP1 allows remote authenticated users to execute arbitrary code via unknown vectors. NOTE: the ADMIN_SP_C issue is already covered by CVE-2008-0699.

Multiple buffer overflows in the JAR file administration routines in the BSU JAVA subcomponent in IBM DB2 8 before FP16, 9.1 before FP4a, and 9.5 before FP1 allow remote authenticated users to cause a denial of service (instance crash) via a call to the (1) RECOVERJAR or (2) REMOVE_JAR procedure with a crafted parameter, related to (a) sqlj.install_jar and (b) sqlj.replace_jar.

Multiple buffer overflows in the DB2 JDBC Applet Server (DB2JDS) service in IBM DB2 9.x and earlier allow remote attackers to (1) execute arbitrary code via a crafted packet to the DB2JDS service on tcp/6789; and cause a denial of service via (2) an invalid LANG parameter or (2) a long packet that generates a "MemTree overflow."

IBM DB2 8.x before 8.1 FixPak 15 and 9.1 before Fix Pack 2 does not properly terminate certain input strings, which allows local users to execute arbitrary code via unspecified environment variables that trigger a heap-based buffer overflow.

Stack-based buffer overflow in IBM DB2 8.x before 8.1 FixPak 15 and 9.1 before Fix Pack 2 allows local users to execute arbitrary code via a long string in unspecified environment variables.
