Detail
Problem Description: Updated ruby packages that fix three security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to do system management tasks. A flaw was found in the way large amounts of memory were allocated on 64-bit systems when using the BigDecimal class. A context-dependent attacker could use this flaw to cause memory corruption, causing a Ruby application that uses the BigDecimal class to crash or, possibly, execute arbitrary code. This issue did not affect 32-bit systems. (CVE-2011-0188) A race condition flaw was found in the remove system entries method in the FileUtils module. If a local user ran a Ruby script that uses this method, a local attacker could use this flaw to delete arbitrary files and directories accessible to that user via a symbolic link attack. (CVE-2011-1004) A flaw was found in the method for translating an exception message into a string in the Exception class. A remote attacker could use this flaw to bypass safe level 4 restrictions, allowing untrusted (tainted) code to modify arbitrary, trusted (untainted) strings, which safe level 4 restrictions would otherwise prevent. (CVE-2011-1005) Red Hat would like to thank Drew Yao of Apple Product Security for reporting the CVE-2011-0188 issue. All Ruby users should upgrade to these updated packages, which contain backported patches to resolve these issues. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 678913 - CVE-2011-1004 Ruby: Symlink race condition by removing directory trees in fileutils module 678920 - CVE-2011-1005 Ruby: Untrusted codes able to modify arbitrary strings 682332 - CVE-2011-0188 ruby: memory corruption in BigDecimal on 64bit platforms |

71640 | Apple Mac OS X Ruby BigDecimal Class Integer Truncation Arbitrary Code Execution |
70958 | Ruby FileUtils.remove_entry_secure Method File Symlink Race Condition Arbitra... Ruby contains a race condition flaw that may allow a malicious local user to delete arbitrary files on the system. The issue is due to the 'FileUtils.remove_entry_secure' method creating temporary files insecurely. It is possible for a local attacker to use a symlink attack to cause the program to unexpectedly write to, or overwrite an attacker specified file. |
70957 | Ruby Exception#to_s Method Safe Level Security Bypass Ruby contains a flaw related to the safe-level feature . The issue is triggered when a context-dependent attacker exploits a flaw within the exception '#to_s' handling. This may allow an attacker to bypass safe-level protection and modify strings via the 'Exception#to_s' method. |
