Synopsis

The remote openSUSE host is missing a security update.

Description

This update for krb5 provides the following fixes :

Security issues fixed :

- CVE-2018-5730: DN container check bypass by supplying special crafted data (bsc#1083927).

- CVE-2018-5729: NULL pointer dereference in kadmind or DN container check bypass by supplying special crafted data (bsc#1083926).

Non-security issues fixed :

- Make it possible for legacy applications (e.g. SAP Netweaver) to remain compatible with newer Kerberos.
System administrators who are experiencing this kind of compatibility issues may set the environment variable GSSAPI_ASSUME_MECH_MATCH to a non-empty value, and make sure the environment variable is visible and effective to the application startup script. (bsc#1057662)

- Fix a GSS failure in legacy applications by not indicating deprecated GSS mechanisms in gss_indicate_mech() list. (bsc#1081725)

This update was imported from the SUSE:SLE-12-SP2:Update update project.

Solution

Update the affected krb5 packages.
