NVD Description

Note: Versions mentioned in the description apply only to the upstream krb5-libs package and not the krb5-libs package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

Double free vulnerability in the init_ctx_reselect function in the SPNEGO initiator in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.10.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via network traffic that appears to come from an intended acceptor, but specifies a security mechanism different from the one proposed by the initiator.
