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.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
