CVE-2017-12133
Use-after-free vulnerability in the clntudp_call function in sunrpc/clnt_udp.c in the GNU C Library (aka glibc or libc6) before 2.26 allows remote attackers to have unspecified impact via vectors related to error path.
Does this matter?
Lower severity and a low EPSS score (2.40%). Track it; it rarely justifies an emergency change on its own.
