A path traversal vulnerability was discovered in uses of TAR files by AppEngine for deployments. This uses a utility to extract files locally for deployment without validating the paths in that deployment don't override system files. This would allow an attacker to override files on the container, POTENTIALLY introducing a MITM type attack vector by replacing libraries or injecting wrapper files. Users are advised to update as soon as possible. For users unable to update disable Google AppEngine deployments and\u002For disable artifacts that provide TARs.","Spinnaker is an open source, multi-cloud continuous delivery platform.

By using special elements such as \"..\" and \"\u002F\" separators, attackers can escape outside of the restricted location to access files or directories that are elsewhere on the system. One of the most common special elements is the \"..\u002F\" sequence, which in most modern operating systems is interpreted as the parent directory of the current location. This is referred to as relative path traversal. Path traversal also covers the use of absolute pathnames such as \"\u002Fusr\u002Flocal\u002Fbin\" to access unexpected files.
