Bash is the standard GNU Bourne Again SHell.
Two vulnerabilities have been found in Bash:
A remote attacker could entice a user to open a specially crafted Bash script, possibly resulting in execution of arbitrary code with the privileges of the process, or a Denial of Service condition of the Bash executable.
A local attacker may be able to perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application or bypass shell access restrictions.
There is no known workaround at this time.
All Bash users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-shells/bash-4.2_p37"
OS | Version | Architecture | Package | Version | Filename |
