ClamAV 0.92 allows local users to overwrite arbitrary files via a symlink attack on (1) temporary files used by the cli_gentempfd function in libclamav/others.c or on (2) .ascii files used by sigtool, when utf16-decode is enabled.
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.
