Suggested advisory:
========================

The updated packages fix security vulnerabilities:

The gdImageCreate function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to cause a denial of service (system hang) via an oversized image. (CVE-2016-9317)

The gdImageCreateFromGd2Ctx function in gd_gd2.c in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to cause a denial of service (application crash) via a crafted image file. (CVE-2016-10167)

Integer overflow in gd_io.c in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to have unspecified impact via vectors involving the number of horizontal and vertical chunks in an image. (CVE-2016-10168)

Updated packages in core/updates_testing:
========================
libwmf-0.2.8.4-32.4.mga5
lib(64)wmf0.2_7-0.2.8.4-32.4.mga5
lib(64)wmf-devel-0.2.8.4-32.4.mga5

from SRPMS:
libwmf-0.2.8.4-32.4.mga5.src.rpm

Prior to testing.

These applications use lib64wmf0.2_7 :
 abiword
 gimp
 graphicsmagick
 imagemagick
 libwmf

libwmf contains several .wmf -> other format conversion programs:
 /usr/bin/wmf2eps
 /usr/bin/wmf2fig
 /usr/bin/wmf2gd
 /usr/bin/wmf2svg
 /usr/bin/wmf2x
No man pages; do <command> --help for good info.

Testing M5_64

BEFORE update:
 libwmf-0.2.8.4-32.3.mga5
 lib64wmf0.2_7-0.2.8.4-32.3.mga5


1. $ wmf2eps -o ac000001.eps ac000001.wmf
Caution: without -o output is to STDOUT.
The output .eps file was OK, opened with several applications.

2. $ wmf2fig -o alamo.fig alamo.wmf
Caution: without -o output is to STDOUT.
Caution: the help implies that the O/P file is .eps rather than .fig . I do not know whether it outputs .eps or .fig, so forced .fig. Despite which, XFig did not list it in its 'open' dialogue. Specifically 'open with XFig' from a file manager window worked; the result was slightly messy, and I could not edit it.

3a. $ wmf2gd -o bcklc140.png bcklc140.wmf
3b. $ wmf2gd -t jpeg -o bcklc140.jpg bcklc140.wmf
This command actually produces a .png (default) or .jpg image. Both results displayed fine.

4. $ wmf2svg -o anima001.svg anima001.wmf
Caution: without -o output is to STDOUT.
The result opened fine in Inkscape (using 'open with Inkscape' from a FM window), and was editable. [discovered a bug re the file open dialogue in Inkscape  *not* to persue here].

5. $ wmf2x bkgr_01.wmf
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
      after 1442 requests (8 known processed) with 0 events remaining.
but the image displayed impecably.

AFTER the update:
 libwmf-0.2.8.4-32.4.mga5
 lib64wmf0.2_7-0.2.8.4-32.4.mga5

All results waere the same as previously.

And to confirm that the library really is called:
 $ strace wmf2svg -o anima001.svg anima001.wmf 2>&1 | grep libwmf
 open("/lib64/libwmf-0.2.so.7", O_RDONLY|O_CLOEXEC) = 3
 open("/lib64/libwmflite-0.2.so.7", O_RDONLY|O_CLOEXEC) = 3

Update OK.

Whiteboard: (none) => MGA5-64-OK

Update installs cleanly on i586.

Using /usr/share/batik/samples/tests/resources/wmf/black_shapes.wmf from the
package batik-demo for testing on Mageia 5 i586.

wmf2svg -o test.svg /usr/share/batik/samples/tests/resources/wmf/black_shapes.wmf

Then using inkscape to view the test.svg.

Validating the update.
