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 heap-based buffer overflow was discovered in bash     when wide characters, not supported by the current     locale set in LC_CTYPE environment variable, are     printed through the echo built-in function. A local     attacker, who can provide data to print through the     `echo -e` built-in function, may use this flaw to crash     a script or execute code with the privileges of the     bash process.(CVE-2012-6711)

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.

A heap-based buffer overflow exists in GNU Bash before 4.3 when wide characters, not supported by the current locale set in the LC_CTYPE environment variable, are printed through the echo built-in function.
A local attacker, who can provide data to print through the 'echo -e' built-in function, may use this flaw to crash a script or execute code with the privileges of the bash process. This occurs because ansicstr() in lib/sh/strtrans.c mishandles u32cconv(). (CVE-2012-6711)

Impact

A local attacker can perform a buffer-overflow attack, which can lead to data corruption, allow the malicious code to be run, or cause the program to terminate.

An update of the bash package has been released.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - bash: when effective UID is not equal to its real UID the saved UID is not dropped (CVE-2019-18276)

  - A heap-based buffer overflow exists in GNU Bash before 4.3 when wide characters, not supported by the     current locale set in the LC_CTYPE environment variable, are printed through the echo built-in function. A     local attacker, who can provide data to print through the echo -e built-in function, may use this flaw     to crash a script or execute code with the privileges of the bash process. This occurs because ansicstr()     in lib/sh/strtrans.c mishandles u32cconv(). (CVE-2012-6711)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
