MiracleLinux 3 : krb5-1.6.1-70.AXS3 (AXSA:2012-256:02)

medium Nessus Plugin ID 284316

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2012-256:02 advisory.

 Kerberos V5 is a trusted-third-party network authentication system, which can improve your network's security by eliminating the insecure practice of cleartext passwords.
 Security issues fixed with this release:
 CVE-2011-1526 ftpd.c in the GSS-API FTP daemon in MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.1 and earlier does not check the krb5_setegid return value, which allows remote authenticated users to bypass intended group access restrictions, and create, overwrite, delete, or read files, via standard FTP commands, related to missing autoconf tests in a configure script.
 Fixed bugs:
 A mistake in the Kerberos libraries could make a client fail to contact a Key Distribution Center or crash if the client already had more than 1024 file descriptors in use. This has been fixed: the Kerberos librairies now use the poll() function instead of the select() function which created those problems.
 If a client request included an authenticator with a subkey, the KDC failed to release memory when processing a ticket-granting server request and consumed an excessive amount of memory. This has been fixed.
 Sometimes, services requiring Kerberos authentication sent two authentication requests to the server. The second one could be flagged as a replay attack and then denied. This has been fixed.
 When Kerberos credentials had expired, the klist command could sometimes crash with a segmentation fault if invoked with the -s option. This has been fixed.
 Multi-line FTP macros could terminate prematurely with a segmentation fault because of a regression. This has been fixed.

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.
