IBM Advanced Settings Utility (ASU) through 3.62 and 3.70 through 9.21 and Bootable Media Creator (BoMC) through 2.30 and 3.00 through 9.21 on Linux allow local users to overwrite arbitrary files via a symlink attack on a (1) temporary file or (2) log file.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
