EulerOS Virtualization 3.0.2.0 : rsync (EulerOS-SA-2023-1729)

high Nessus Plugin ID 175208

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the rsync package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. (CVE-2018-25032)

 - An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file). (CVE-2022-29154)

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 rsync packages.
