PatchLink Update client for Unix, as used by Novell ZENworks Patch Management Update Agent for Linux/Unix/Mac (LUM) 6.2094 through 6.4102 and other products, allows local users to (1) truncate arbitrary files via a symlink attack on the /tmp/patchlink.tmp file used by the logtrimmer script, and (2) execute arbitrary code via a symlink attack on the /tmp/plshutdown file used by the rebootTask script.
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.
