Buffer overflow in sqllib/security/db2ckpw for IBM DB2 Universal Database 6.0 and 7.0 allows local users to execute arbitrary code via a long username that is read from a file descriptor argument.
IBM DB2 7.0 allows a remote attacker to cause a denial of service (crash) via a single byte to (1) db2ccs.exe on port 6790, or (2) db2jds.exe on port 6789.
IBM DB2 Universal Database 7 before FixPak 12 creates certain DMS directories with insecure permissions (777), which allows local users to modify or delete certain DB2 files.
IBM DB2 7.1 and 8.1 allow the bin user to gain root privileges by modifying the shared libraries that are used in setuid root programs.
Multiple stack-based buffer overflows in IBM DB2 7.x and 8.1 allow local users to execute arbitrary code via (1) a long third argument to the rec2xml function or (2) a long filename argument to the generatedistfile procedure.
Stack-based buffer overflow in the SATENCRYPT function in IBM DB2 8.1, when Satellite Administration (SATADMIN) is enabled, allows remote attackers to execute arbitrary code via a long parameter.
Stack-based buffer overflow in JDBC Applet Server in IBM DB2 8.1 allows remote attackers to execute arbitrary by connecting and sending a long username, then disconnecting gracefully and reconnecting and sending a short username and an unexpected db2java.zip version, which causes a null terminator to be removed and leads to the overflow.
Stack-based buffer overflow in libdb2.so in IBM DB2 7.x and 8.1 allows local users to execute arbitrary code via a long DB2LPORT environment variable.
Stack-based buffer overflow in call in IBM DB2 7.x and 8.1 allows remote attackers to execute arbitrary code via a long libname.
Stack-based buffer overflow in db2fmp in IBM DB2 7.x and 8.1 allows local users to execute arbitrary code via a long parameter.
Unknown "high risk" vulnerability in DB2 Universal Database 8.1 and earlier has unknown impact and attack vectors. NOTE: due to the delayed disclosure of details for this issue, this candidate may be SPLIT in the future. In addition, this may be a duplicate of other issues as reported by the vendor.
