libwmf - security update

Agostino Sarubbo from Gentoo discovered a flaw in libwmf’s Windows
Metafile Format (WMF) parser which caused allocation of excessive
amount of memory potentially leading to a crash.

For Debian 7 Wheezy, these problems have been fixed in version
0.2.8.4-10.3+deb7u2.

We recommend that you upgrade your libwmf packages.
