CVE-2016-9445
Integer overflow in the vmnc decoder in the gstreamer allows remote attackers to cause a denial of service (crash) via large width and height values, which triggers a buffer overflow.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.84%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
