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 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.
