CVE-2015-8629 Open this link in a new tabHow to fix?
Upgrade Debian:10 krb5 to version 1.13.2+dfsg-5 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream krb5 package and not the krb5 package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
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.
