SynopsisThe remote EulerOS host is missing a security update.
DescriptionAccording to the version of the zsh package installed, the EulerOS installation on the remote host is affected by the following vulnerability :
- In Zsh before 5.8, attackers able to execute commands can regain privileges dropped by the --no-PRIVILEGED option. Zsh fails to overwrite the saved uid, so the original privileges can be restored by executing MODULE_PATH=/dir/with/module zmodload with a module that calls setuid().(CVE-2019-20044)
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.
SolutionUpdate the affected zsh package.
