Subject: CVE-2022-37865: Apache Ivy allow create/overwrite any file on the system
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Severity: medium
Description:
With Apache Ivy 2.4.0 an optional packaging attribute has been
introduced that allows artifacts to be unpacked on the fly if they used
pack200 or zip packaging.
For artifacts using the "zip", "jar" or "war" packaging Ivy prior to
2.5.1 doesn't verify the target path when extracting the archive. An
archive containing absolute paths or paths that try to traverse
"upwards" using ".." sequences can then write files to any location on
the local fie system that the user executing Ivy has write access to.
Mitigation:
Ivy users of version 2.4.0 to 2.5.0 should upgrade to Ivy 2.5.1.
