EulerOS 2.0 SP8 : wget (EulerOS-SA-2019-1663)

high Nessus Plugin ID 126290

Synopsis

The remote EulerOS host is missing a security update.

Description

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

- set_file_metadata in xattr.c in GNU Wget before 1.20.1 stores a file's origin URL in the user.xdg.origin.url metadata attribute of the extended attributes of the downloaded file, which allows local users to obtain sensitive information (e.g., credentials contained in the URL) by reading this attribute, as demonstrated by getfattr. This also applies to Referer information in the user.xdg.referrer.url metadata attribute. According to 2016-07-22 in the Wget ChangeLog, user.xdg.origin.url was partially based on the behavior of fwrite_xattr in tool_xattr.c in curl.(CVE-2018-20483)

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 wget package.
