GHSA-h9mw-grgx-2fhf sbt vulnerable to arbitrary file write via archive extraction (Zip Slip)

• Maven org.scala-sbt:sbt: >= 0.3.4, < 1.9.7 → fixed in 1.9.7 • Maven org.scala-sbt:io_2.12: >= 1.0.0, < 1.9.7 → fixed in 1.9.7 • Maven org.scala-sbt:io_2.13: >= 1.0.0, < 1.9.7 → fixed in 1.9.7 • Maven org.scala-sbt:io_3: >= 1.0.0, < 1.9.7 → fixed in 1.9.7

Impact Given specially crafted zip or JAR file, `IO.unzip` allows writing of arbitrary file. The follow is an example of a malicious entry: ``` +2018-04-15 22:04:42 ..... 20 20 ../../../../../../root/.ssh/authorized_keys ``` This would have a potential to overwrite `/root/.ssh/authorized_keys`. Within sbt's main code, `IO.unzip` is used in `pullRemoteCache` task and `Resolvers.remote`; however many projects use `IO.unzip(...)` directly to implement custom tasks - https://github.com/search?q=IO.unzip+language%3AScala&type=code&l=Scala&p=1 Patches The problem has been patched in https://github.com/sbt/io/pull/360 sbt 1.9.7 is available with the fix. Workarounds A workaround might be use some other library to unzip.
