[Backports-security-announce] Security Update for nsrp

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

CVE-2009-0689

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.

CVE-2009-2463

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 2.0.0.24, 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&gt;

We recommend to pin the backports repository to 200 so that new
versions of installed backports will be installed automatically.
