Scientific Linux Security Update : krb5-appl on SL6.x i386/x86_64

medium Nessus Plugin ID 61079

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

The krb5-appl packages provide Kerberos-aware telnet, ftp, rcp, rsh, and rlogin clients and servers. While these have been replaced by tools such as OpenSSH in most environments, they remain in use in others.

It was found that gssftp, a Kerberos-aware FTP server, did not properly drop privileges. A remote FTP user could use this flaw to gain unauthorized read or write access to files that are owned by the root group. (CVE-2011-1526)

Solution

Update the affected krb5-appl-clients and / or krb5-appl-servers packages.
