AV:N/AC:L/Au:N/C:N/I:N/A:P
Francisco Alonso of Red Hat Product Security found an issue in the file
utility, whose code is embedded in PHP, a general-purpose scripting
language. When checking ELF files, note headers are incorrectly
checked, thus potentially allowing attackers to cause a denial of
service (out-of-bounds read and application crash) by supplying a
specially crafted ELF file.
As announced in DSA-3064-1 it has been decided to follow the stable
5.4.x releases for the Wheezy php5 packages. Consequently the
vulnerability is addressed by upgrading PHP to a new upstream version
5.4.35, which includes additional bug fixes, new features and possibly
incompatible changes. Please refer to the upstream changelog for more
information:
For the stable distribution (wheezy), this problem has been fixed in
version 5.4.35-0+deb7u1.
We recommend that you upgrade your php5 packages.
