Linux Advisory Watch Thank you for reading the LinuxSecurity.com weekly security newsletter. The purpose of this document is to provide our readers with a quick summary of each week's most relevant Linux security headline. Vulnerabilities affect nearly every vendor virtually every week, so be sure to read through to find the updates your distributor have made available.

LinuxSecurity.com Feature Extras:

Review: Googling Security: How Much Does Google Know About You - If I ask "How much do you know about Google?" You may not take even a second to respond. But if I may ask "How much does Google know about you"? You may instantly reply "Wait... what!? Do they!?" The book "Googling Security: How Much Does Google Know About You" by Greg Conti (Computer Science Professor at West Point) is the first book to reveal how Google's vast information stockpiles could be used against you or your business – and what you can do to protect yourself.

A Secure Nagios Server - Nagios is a monitoring software designed to let you know about problems on your hosts and networks quickly. You can configure it to be used on any network. Setting up a Nagios server on any Linux distribution is a very quick process however to make it a secure setup it takes some work. This article will not show you how to install Nagios since there are tons of them out there but it will show you in detail ways to improve your Nagios security.

http://www.linuxsecurity.com/content/view/151467
  Mandriva: bind (Jan 19)
 

Some vulnerabilities were discovered and corrected in bind: The original fix for CVE-2009-4022 was found to be incomplete. BIND was incorrectly caching certain responses without performing proper DNSSEC validation. CNAME and DNAME records could be cached, without proper DNSSEC validation, when received from processing recursive client queries that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries (CVE-2010-0290). There was an error in the DNSSEC NSEC/NSEC3 validation code that could cause bogus NXDOMAIN responses (that is, NXDOMAIN responses for records proven by NSEC or NSEC3 to exist) to be cached as if they had validated correctly, so that future queries to the resolver would return the bogus NXDOMAIN with the AD flag set (CVE-2010-0097). Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers. Additionally BIND has been upgraded to the latest patch release version.

http://www.linuxsecurity.com/content/view/151465
  Mandriva: gzip (Jan 19)
 

Multiple vulnerabilities has been found and corrected in gzip: A missing input sanitation flaw was found in the way gzip used to decompress data blocks for dynamic Huffman codes. A remote attacker could provide a specially-crafted gzip compressed data archive, which once opened by a local, unsuspecting user would lead to denial of service (gzip crash) or, potentially, to arbitrary code execution with the privileges of the user running gzip (CVE-2009-2624). An integer underflow leading to array index error was found in the way gzip used to decompress files / archives, compressed with the Lempel-Ziv-Welch (LZW) compression algorithm. A remote attacker could provide a specially-crafted LZW compressed gzip archive, which once decompressed by a local, unsuspecting user would lead to gzip crash, or, potentially to arbitrary code execution with the privileges of the user running gzip (CVE-2010-0001). Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers. The updated packages have been patched to correct these issues.

  Mandriva: wireshark (Jan 19)
 

This advisory updates wireshark to the latest 1.2.5 version, fixing several bugs and two security issues: - The (1) SMB and (2) SMB2 dissectors in Wireshark 0.9.0 through 1.2.4 allow remote attackers to cause a denial of service (crash) via a crafted packet (CVE-2009-4377) - Buffer overflow in the daintree_sna_read function in the Daintree SNA file parser in Wireshark 1.2.0 through 1.2.4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted packet (CVE-2009-4376)

http://www.linuxsecurity.com/content/view/151446
  Mandriva: phpMyAdmin (Jan 19)
 

Multiple vulnerabilities has been found and corrected in phpMyAdmin: libraries/File.class.php in phpMyAdmin 2.11.x before 2.11.10 creates a temporary directory with 0777 permissions, which has unknown impact and attack vectors (CVE-2008-7251). libraries/File.class.php in phpMyAdmin 2.11.x before 2.11.10 uses predictable filenames for temporary files, which has unknown impact and attack vectors (CVE-2008-7252). scripts/setup.php (aka the setup script) in phpMyAdmin 2.11.x before 2.11.10 calls the unserialize function on the values of the (1) configuration and (2) v[0] parameters, which might allow remote attackers to conduct cross-site request forgery (CSRF) attacks via unspecified vectors (CVE-2009-4605). This update provides phpMyAdmin 2.11.10, which is not vulnerable to these issues.

http://www.linuxsecurity.com/content/view/151445
  Mandriva: ruby (Jan 18)

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers. The updated packages have been patched to correct this issue.

http://www.linuxsecurity.com/content/view/151444
  Mandriva: roundcubemail (Jan 18)
 

Multiple vulnerabilities has been found and corrected in transmission: A number of dependency probles were discovered and has been corrected with this release (#56006). Cross-site request forgery (CSRF) vulnerability in Roundcube Webmail 0.2.2 and earlier allows remote attackers to hijack the authentication of unspecified users for requests that modify user information via unspecified vectors, a different vulnerability than CVE-2009-4077 (CVE-2009-4076). Cross-site request forgery (CSRF) vulnerability in Roundcube Webmail 0.2.2 and earlier allows remote attackers to hijack the authentication of unspecified users for requests that send arbitrary emails via unspecified vectors, a different vulnerability than CVE-2009-4076 (CVE-2009-4077). The updated packages have been patched to correct these issues. Additionally roundcubemail has been upgraded to 0.2.2 that also fixes a number of upstream bugs.

http://www.linuxsecurity.com/content/view/151424
  Mandriva: mysql (Jan 17)
 

Multiple vulnerabilities has been found and corrected in mysql: mysqld in MySQL 5.0.x before 5.0.88 and 5.1.x before 5.1.41 does not (1) properly handle errors during execution of certain SELECT statements with subqueries, and does not (2) preserve certain null_value flags during execution of statements that use the GeomFromWKB function, which allows remote authenticated users to cause a denial of service (daemon crash) via a crafted statement (CVE-2009-4019). The vio_verify_callback function in viosslfactories.c in MySQL 5.0.x before 5.0.88 and 5.1.x before 5.1.41, when OpenSSL is used, accepts a value of zero for the depth of X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary SSL-based MySQL servers via a crafted certificate, as demonstrated by a certificate presented by a server linked against the yaSSL library (CVE-2009-4028). MySQL 5.1.x before 5.1.41 allows local users to bypass certain privilege checks by calling CREATE TABLE on a MyISAM table with modified (1) DATA DIRECTORY or (2) INDEX DIRECTORY arguments that are originally associated with pathnames without symlinks, and that can point to tables created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the MySQL data home directory, related to incorrect calculation of the mysql_unpacked_real_data_home value. NOTE: this vulnerability exists because of an incomplete fix for CVE-2008-4098 and CVE-2008-2079 (CVE-2009-4030). The updated packages have been patched to correct these issues. Additionally for 2009.1 and 2010.0 mysql has also been upgraded to the latest stable 5.1 release (5.1.42).

  Mandriva: mkinitrd (Jan 15)
 

When a system uses dmraid, mkinitrd now calls dmraid command with the option --rm_partitions. This option is only available in new dmraid package, so boot will fail if, during an upgrade, initrd is generated with new mkinitrd and old dmraid (#55427). This updated package adds this dependency. Additionally, two bug were fixed about drm modules inclusion (#55676). First, when a drm module was loaded at the time mkinitrd is run, it would be included even if it not in DRM_WHITELIST. Then, when a module was whitelisted, all the drm modules for this hardware where included, including proprietary ones).
