Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing a security update.

Description

According to the version of the bash package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

- A privilege escalation vulnerability was found in bash in the way it dropped privileges when started with an effective user id not equal to the real user id. Bash may be vulnerable to this flaw if the setuid permission is set and the owner of the bash program itself is a non-root user. A local attacker could exploit this flaw to escalate their privileges on the system.(CVE-2019-18276)
