CVE-2015-8629 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. The xdr_nullstring function in lib/kadm5/kadm_rpc_xdr.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 does not verify whether '\0' characters exist as expected, which allows remote authenticated users to obtain sensitive information or cause a denial of service (out-of-bounds read) via a crafted string.. EPSS estimates a 3.66% chance of exploitation in the next 30 days.
