Gentoo Linux Security Advisory

Title: Bash: Multiple vulnerabilities (GLSA 201210-05)
Severity: normal
Exploitable: local
Date: October 20, 2012
Bug(s): #251319, #431850
ID: 201210-05

Synopsis

Two vulnerabilities have been found in Bash, the worst of which may
allow execution of arbitrary code.


Background

Bash is the standard GNU Bourne Again SHell.

Affected Packages

Package: app-shells/bash
Vulnerable: < 4.2_p37
Unaffected: >= 4.2_p37
Architectures: All supported architectures


Description

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.

Resolution

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