Security Features of Firefox 3.0
--------------------------------
Lets take a look at the security features of the newly released Firefox
3.0. Since it's release on Tuesday I have been testing it out to see
how the new security enhancements work and help in increase user
browsing security.  One of the exciting improvements for me was how
Firefox handles SSL secured web sites while browsing the Internet.
There are also many other security features that this article will look
at. For example, improved plugin and addon security.

Read on for more security features of Firefox 3.0.

Review: The Book of Wireless
----------------------------
"The Book of Wireless" by John Ross is an answer to the problem of
learning about wireless networking. With the wide spread use of
Wireless networks today anyone with a computer should at least know the
basics of wireless. Also, with the wireless networking, users need to
know how to protect themselves from wireless networking attacks.

* EnGarde Secure Community 3.0.19 Now Available! (Apr 15)
  -------------------------------------------------------
  Guardian Digital is happy to announce the release of EnGarde Secure
  Community 3.0.19 (Version 3.0, Release 19).  This release includes
  many updated packages and bug fixes and some feature enhancements to
  the EnGarde Secure Linux Installer and the SELinux policy.

http://www.linuxsecurity.com/content/view/136174 

------------------------------------------------------------------------

* Debian: New afuse packages fix privilege escalation (Jul 16)
  ------------------------------------------------------------
  Anders Kaseorg discovered that afuse, an automounting file system in
  user-space, did not properly escape meta characters in paths. This
  allowed a local attacker with read access to the filesystem to
  execute commands as the owner of the filesystem.

http://www.linuxsecurity.com/content/view/139936 

* Debian: New pdns-recursor packages fix predictable randomness (Jul 16)
  ----------------------------------------------------------------------
  Thomas Biege discovered that the upstream fix for the weak random
  number generator released in DSA-1544-1 was incomplete:  Source port
  randomization did still not use difficult-to-predict random numbers.
  This is corrected in this security update.

http://www.linuxsecurity.com/content/view/139935 

* Debian: New cacti packages fix regression (Jul 15)
  --------------------------------------------------
  Since the previous security update, the cacti package could no longer
  be rebuilt from the source package. This update corrects that
  problem. Note that this problem does not affect regular use of the
  provided binary packages (.deb).

http://www.linuxsecurity.com/content/view/139921 

* Debian: New gaim packages fix execution of arbitrary code (Jul 15)
  ------------------------------------------------------------------
  It was discovered that gaim, an multi-protocol instant messaging
  client, was vulnerable to several integer overflows in its MSN
  protocol handlers. These could allow a remote attacker to execute
  arbitrary code.

http://www.linuxsecurity.com/content/view/139919 

* Debian: New lighttpd packages fix multiple DOS issues (Jul 15)
  --------------------------------------------------------------
  Several local/remote vulnerabilities have been discovered in
  lighttpd, a fast webserver with minimal memory footprint.

http://www.linuxsecurity.com/content/view/139918 

* Debian: New iceweasel packages fix several vulnerabilities (Jul 11)
  -------------------------------------------------------------------
  Devon Hubbard, Jesse Ruderman and Martijn Wargers discovered crashes
  in the layout engine, which might allow the execution of arbitrary
  code.

http://www.linuxsecurity.com/content/view/139768 

------------------------------------------------------------------------

* Gentoo: Mercurial Directory traversal (Jul 15)
  ----------------------------------------------
  A directory traversal vulnerability in
  Mercurial allows for the renaming of arbitrary files.

http://www.linuxsecurity.com/content/view/139922 

* Gentoo: BIND Cache poisoning (Jul 11)
  -------------------------------------
  A weakness in the DNS protocol has been reported, which could lead to
  cache poisoning on recursive resolvers.

http://www.linuxsecurity.com/content/view/139769 

------------------------------------------------------------------------

* Mandriva: Updated pcre packages fix vulnerability (Jul 16)
  ----------------------------------------------------------
  Tavis Ormandy of the Google Security Team discovered a heap-based
  buffer overflow when compiling certain regular expression patterns.
  This could be used by a malicious attacker by sending a specially
  crafted regular expression to an application using the PCRE library,
  resulting in the possible execution of arbitrary code or a denial of
  service (CVE-2008-2371). The updated packages have been patched to
  correct this issue.

http://www.linuxsecurity.com/content/view/139926 

* Mandriva: Updated x11-server packages fix offscreen pixmaps drawing issue (Jul 16)
  ----------------------------------------------------------------------------------
  This x11-sever update disables offscreen pixmaps by default as they
  were causing drawing issues with Firefox 3 and other applications. To
  re-enable this option, use 'Option XaaOffscreenPixmaps on' in
  xorg.conf.

http://www.linuxsecurity.com/content/view/139925 

* Mandriva: Updated poppler packages fix arbitrary code execution vulnerability (Jul 15)
  --------------------------------------------------------------------------------------
  A memory management issue was found in libpoppler by Felipe Andres
  Manzano that could allow for the execution of arbitrary code with the
  privileges of the user running a poppler-based application, if they
  opened a specially crafted PDF file (CVE-2008-2950). The updated
  packages have been patched to correct this issue.

http://www.linuxsecurity.com/content/view/139923 

* Mandriva: Updated bluez/bluez-utils packages fix SDP packet parsing vulnerability (Jul 15)
  ------------------------------------------------------------------------------------------
  An input validation flaw was found in the Bluetooth Session
  Description Protocol (SDP) packet parser used in the Bluez bluetooth
  utilities. A bluetooth device with an already-trusted relationship,
  or a local user registering a service record via a UNIX socket or
  D-Bus interface, could cause a crash and potentially execute
  arbitrary code with the privileges of the hcid daemon
  (CVE-2008-2374). The updated packages have been patched to correct
  this issue.

http://www.linuxsecurity.com/content/view/139786 

* Mandriva: Updated openldap packages fix slapd DoS vulnerability (Jul 12)
  ------------------------------------------------------------------------
  A denial of service vulnerability was discovered in the way the
  OpenLDAP slapd daemon processed certain network messages. An
  unauthenticated remote attacker could send a specially crafted
  request that would crash the slapd daemon (CVE-2008-2952). The
  updated packages have been patched to correct this issue.

http://www.linuxsecurity.com/content/view/139773 

* Mandriva: Updated OpenOffice.org packages fix vulnerability (Jul 11)
  --------------------------------------------------------------------
  Integer overflow in the rtl_allocateMemory function in
  sal/rtl/source/alloc_global.c in OpenOffice.org (OOo) 2.0 through 2.4
  allows remote attackers to execute arbitrary code via a crafted file
  that triggers a heap-based buffer overflow. The updated packages have
  been patched to fix the issue.

http://www.linuxsecurity.com/content/view/139772 

* Mandriva: Updated pidgin packages fix MSN protocol handler vulnerability (Jul 10)
  ---------------------------------------------------------------------------------
  An integer overflow flaw was found in Pidgin's MSN protocol handler
  that could allow for the execution of arbitrary code if a user
  received a malicious MSN message (CVE-2008-2927). In addition, this
  update provides the ability to use ICQ networks again on Mandriva
  Linux 2008.0, as in MDVA-2008:103 (updated pidgin for 2008.1). The
  updated packages have been patched to correct this issue.

http://www.linuxsecurity.com/content/view/139758 

------------------------------------------------------------------------

* SuSE: bind (SUSE-SA:2008:033) (Jul 11)

  poisoning attacks    possible because of the "birthday paradox" and
  an attack discovered by Dan	 Kaminsky. Unfortunately we do not have
  details about Kaminsky's attack and	 have to trust the statement
  that a random UDP source-port is sufficient to    stop it.
