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.
Summary: On September 24, 2014 the United States Computer Emergency Readiness Team (US-CERT) released a security bulletin regarding a newly discovered vulnerability within the GNU Bourne Again Shell (Bash), which could allow an attacker to execute arbitrary code on a target machine.
Based on the design of the Canvas platform, and active security/access controls, we determined that the risk to the Canvas platform was very low, but felt it prudent to patch all systems to remove any potential for an attack or exploit.
All systems were patched for both CVEs as of September 27, 2014
