GLSA-201210-05 : Bash: Multiple vulnerabilities
Medium Nessus Plugin ID 62650
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201210-05 (Bash: Multiple vulnerabilities)
Two vulnerabilities have been found in Bash:
Bash example scripts do not handle temporary files securely (CVE-2008-5374).
Improper bounds checking in Bash could cause a stack-based buffer overflow (CVE-2012-3410).
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.
SolutionAll Bash users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-shells/bash-4.2_p37'
