MiracleLinux 4 : sssd-1.12.4-47.AXS4.4 (AXSA:2015-557:03)

medium Nessus Plugin ID 289032

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2015-557:03 advisory.

Provides a set of daemons to manage access to remote directories and authentication mechanisms. It provides an NSS and PAM interface toward the system and a pluggable backend system to connect to multiple different account sources. It is also the basis to provide client auditing and policy services for projects like FreeIPA.
Security issues fixed with this release:
CVE-2015-5292 Memory leak in the Privilege Attribute Certificate (PAC) responder plugin (sssd_pac_plugin.so) in System Security Services Daemon (SSSD) 1.10 before 1.13.1 allows remote authenticated users to cause a denial of service (memory consumption) via a large number of logins that trigger parsing of PAC blobs during Kerberos authentication.
Fixed bugs:
* Previously, SSSD did not correctly handle sudo rules that applied to groups with names containing special characters, such as the ( opening parenthesis sign. Consequently, SSSD skipped such sudo rules.
The internal sysdb search has been modified to escape special characters when searching for objects to which sudo rules apply. As a result, SSSD applies the described sudo rules as expected.
* Prior to this update, SSSD did not correctly handle group names containing special Lightweight Directory Access Protocol (LDAP) characters, such as the ( or ) parenthesis signs. When a group name contained one or more such characters, the internal cache cleanup operation failed with an I/O error. With this update, LDAP special characters in the Distinguished Name (DN) of a cache entry are escaped before the cleanup operation starts. As a result, the cleanup operation completes successfully in the described situation.
* Applications performing Kerberos authentication previously increased the memory footprint of the Kerberos plug-in that parses the Privilege Attribute Certificate (PAC) information. The plug-in has been updated to free the memory it allocates, thus fixing this bug.
* Previously, when malformed POSIX attributes were defined in an Active Directory (AD) LDAP server, SSSD unexpectedly switched to offline mode. This update relaxes certain checks for AD POSIX attribute validity.
As a result, SSSD now works as expected even when malformed POSIX attributes are present in AD and no longer enters offline mode in the described situation.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
