Description

It was discovered that libimobiledevice incorrectly handled socket permissions. A remote attacker could use this issue to access services on iOS devices, contrary to expectations.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
