Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

In Apache Tika 0.9 to 1.18, in a rare edge case where a user does not specify an extract directory on the commandline (--extract-dir=) and the input file has an embedded file with an absolute path, such as "C:/evil.bat", tika-app would overwrite that file.
