What is CVE-2015-2698?
CVE-2015-2698 is a high-severity memory corruption vulnerability in Mit Kerberos 5, published on 13 Nov 2015. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The iakerb_gss_export_sec_context function in lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) 1.14 pre-release 2015-09-14 improperly accesses a certain pointer, which allows remote authenticated users to cause a denial of service (memory corruption) or possibly have unspecified other impact by interacting with an application that calls the gss_export_sec_context function. NOTE: this vulnerability exists because of an incorrect fix for CVE-2015-2696.
