Apache Ivy: PackagerResolver path traversal vulnerability

The PackagerResolver of Apache Ivy is able to download online
artifacts and to (re)package them in a format defined by a
packager.xml file. This repackaging is done by an Ant script, which is
stored in a subdirectory of the configured "buildRoot" directory. This
subdirectory is calculated based on modules coordinates, like the
organisation, name or version.

If one of the coordinates contains "../" sequences - which are valid
characters for Ivy coordinates in general- it is possible to break out
of the configured "buildRoot" directory where other files can be
overwritten.

In order to exploit this vulnerability an attacker needs to have
access to a packager repository and add or modify the coordinates in
ivy.xml files to have such "../" sequences.

Users of Apache Ivy 2.0.0 to 2.5.3 (inclusive) should upgrade to Ivy 2.6.0.

CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
