GLSA-201210-05 : Bash: Multiple vulnerabilities

medium Nessus Plugin ID 62650

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The 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).
 Impact :

 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.
 Workaround :

 There is no known workaround at this time.

Solution

All Bash users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-shells/bash-4.2_p37'
