"libwmf was updated to fix four security issues.

These security issues were fixed :

  - CVE-2015-4588: Heap-based buffer overflow in the
    DecodeImage function allowed remote attackers to cause a
    denial of service (crash) or possibly execute arbitrary
    code via a crafted 'run-length count' in an image in a
    WMF file (bsc#933109).

  - CVE-2015-0848: Heap-based buffer overflow allowed remote
    attackers to cause a denial of service (crash) or
    possibly execute arbitrary code via a crafted BMP image
    (bsc#933109).

  - CVE-2015-4696: Use-after-free vulnerability allowed
    remote attackers to cause a denial of service (crash)
    via a crafted WMF file to the (1) wmf2gd or (2) wmf2eps
    command (bsc#936062).

  - CVE-2015-4695: meta.h allowed remote attackers to cause
    a denial of service (out-of-bounds read) via a crafted
    WMF file (bsc#936058).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
