[Backports-security-announce] Security Update for nsrp

Alexander Reichle-Schmehl uploaded new packages for nspr which fixed the
following security problems:


  Array index error in the (1) dtoa implementation in dtoa.c (aka
  pdtoa.c) and the (2) gdtoa (aka new dtoa) implementation in gdtoa/misc.c
  in libc, as used in multiple operating systems and products including in
  FreeBSD 6.4 and 7.2, NetBSD 5.0, OpenBSD 4.5, Mozilla Firefox 3.0.x
  before 3.0.15 and 3.5.x before 3.5.4, K-Meleon 1.5.3, SeaMonkey 1.1.8,
  and other products, allows context-dependent attackers to cause a denial
  of service (application crash) and possibly execute arbitrary code via a
  large precision value in the format argument to a printf function, which
  triggers incorrect memory allocation and a heap-based buffer overflow
  during conversion to a floating-point number.


  Multiple integer overflows in the (1) PL_Base64Decode and (2)
  PL_Base64Encode functions in nsprpub/lib/libc/src/base64.c in Mozilla
  Firefox before 3.0.12, Thunderbird before, and SeaMonkey before
  1.1.19 allow remote attackers to cause a denial of service (memory
  corruption and application crash) or possibly execute arbitrary code via
  unspecified vectors that trigger buffer overflows.

For the lenny-backports distribution the problems have been fixed in
version 4.8.4-2~bpo50+1.

For the squeeze and sid distributions the problems have been fixed in
version 4.8.4-2.

Upgrade instructions
If you don't use pinning (see [1]) you have to update the package
manually via "apt-get -t lenny-backports install <packagelist>" with
the packagelist of your installed packages affected by this update.
[1] <http://backports.org/dokuwiki/doku.php?id=instructions>
We recommend to pin the backports repository to 200 so that new
versions of installed  backports will be installed automatically. 
  Package: *
  Pin: release a=lenny-backports
