A remote exploit vulnerability in bash has been discovered in Linux, which will allow attackers to execute arbitrary code.
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution.
The severity of this exploit is high, and you should look to update bash on all of your linux machines as soon as possible.
Please contact us if you require any support in updating your servers or machines
This affects all versions of Bash through version 4.3. Check and update to a patched version.
