CVE-2016-4973
Binaries compiled against targets that use the libssp library in GCC for stack smashing protection (SSP) might allow local users to perform buffer overflow attacks by leveraging lack of the Object Size Checking feature.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
