mktexlsr revision 36855, and before revision 36626 as packaged in texlive allows local users to write to arbitrary files via a symlink attack. NOTE: this vulnerability exists due to the reversion of a fix of CVE-2015-5700.
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.
