EulerOS 2.0 SP3 : xz (EulerOS-SA-2022-1775)

high Nessus Plugin ID 161522

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the xz packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system. (CVE-2022-1271)

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 xz packages.
