Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the tar package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - GNU Tar through 1.30, when --sparse is used, mishandles file shrinkage during read access, which allows local users to cause a denial of service (infinite read loop in sparse_dump_region in sparse.c) by modifying a file that is supposed to be archived by a different user's process (e.g., a system backup running as root).(CVE-2018-20482)

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

Solution

Update the affected tar package.
