CVE-2015-5229
The calloc function in the glibc package in Red Hat Enterprise Linux (RHEL) 6.7 and 7.2 does not properly initialize memory areas, which might allow context-dependent attackers to cause a denial of service (hang or crash) via unspecified vectors.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
