FreeIPA 4.8.3 is a security update release that includes fixes for two issues :

  - CVE-2019-10195: Don't log passwords embedded in commands     in calls using batch A flaw was found in the way that     FreeIPA's batch processing API logged operations. This     included passing user passwords in clear text on FreeIPA     masters. Batch processing of commands with passwords as     arguments or options is not performed by default in     FreeIPA but is possible by third-party components. An     attacker having access to system logs on FreeIPA masters     could use this flaw to produce log file content with     passwords exposed. The issue was reported by Jamison     Bennett from Cloudera

  - CVE-2019-14867: Make sure to have storage space for tag     A flaw was found in the way the internal function     ber_scanf() was used in some components of the IPA     server, which parsed kerberos key data. An     unauthenticated attacker who could trigger parsing of     the krb principal key could cause the IPA server to     crash or in some conditions, cause arbitrary code to be     executed on the server hosting the IPA server. The issue     was reported by Todd Lipcon from Cloudera

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A flaw was found in IPA, all 4.6.x versions before 4.6.7, all 4.7.x versions before 4.7.4 and all 4.8.x versions before 4.8.3, in the way the internal function ber_scanf() was used in some components of the IPA server, which parsed kerberos key data. An unauthenticated attacker who could trigger parsing of the krb principal key could cause the IPA server to crash or in some conditions, cause arbitrary code to be executed on the server hosting the IPA server.
