[DLA 674-2] ghostscript regression update

Package : ghostscript
Version : 9.05~dfsg-6.3+deb7u4
Debian Bug : 840691


The update for ghostscript issued as DLA-674-1 caused regressions for
certain Postscript document viewers (evince, zathura). Updated packages
are now available to address this problem. For reference, the original
advisory text follows.

Several vulnerabilities were discovered in Ghostscript, the GPL
PostScript/PDF interpreter, which may lead to the execution of arbitrary
code or information disclosure if a specially crafted Postscript file is
processed.

For Debian 7 "Wheezy", these problems have been fixed in version
9.05~dfsg-6.3+deb7u4.

We recommend that you upgrade your ghostscript packages.

[DLA 680-2] bash version number correction

Package : bash
Version : 4.2+dfsg-0.1+deb7u4
CVE ID : CVE-2016-7543

This is a correction of DLA 680-1 that mentioned that
bash 4.2+dfsg-0.1+deb7u3 was corrected. The corrected package
version was 4.2+dfsg-0.1+deb7u4.

For completeness the text from DLA 680-1 available below with
only corrected version information. No other changes.

An old attack vector has been corrected in bash (a sh-compatible
command language interpreter).

CVE-2016-7543
Specially crafted SHELLOPTS+PS4 environment variables in combination
with insecure setuid binaries.

The setuid binary had to both use setuid() function call in
combination with a system() or popen() function call. With this
combination it is possible to gain root access.

I addition bash have to be the default shell (/bin/sh have to point
to bash) for the system to be vulnerable.

The default shell in Debian is dash and there are no known setuid
binaries in Debian with the, above described, insecure combination.

There could however be local software with the, above described,
insecure combination that could benefit from this correction.

For Debian 7 "Wheezy", this problem have been fixed in version
4.2+dfsg-0.1+deb7u4.

We recommend that you upgrade your bash packages.

If there are local software that have the insecure combination and
do a setuid() to some other user than root, then the update will not
correct that problem. That problem have to be addressed in the
insecure setuid binary.

It was discovered that there was a possible DoS attack in Cairo, a
multi-platform library providing vector-based rendering. An SVG could
generate invalid pointers from a _cairo_image_surface in write_png.

For Debian 7 "Wheezy", this issue has been fixed in cairo version
1.12.2-3+deb7u1.

We recommend that you upgrade your cairo packages.
