Summary

GNU Bash through version 4.3 is affected, and it can be triggered through software that passes environment variables across a privilege boundary, such as OpenSSH's ForceCommand feature, Apache HTTP Server's mod_cgi and mod_cgid modules, and DHCP client scripts. A remote attacker could use a specially crafted environment to write to files or potentially cause other unspecified effects.

Read the original description

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact 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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.
