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.
