CVE-2015-7236
Use-after-free vulnerability in xprt_set_caller in rpcb_svc_com.c in rpcbind 0.2.1 and earlier allows remote attackers to cause a denial of service (daemon crash) via crafted packets, involving a PMAP_CALLIT code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
