RHEL 6 : krb5-appl (RHSA-2011:0920)

Synopsis

The remote Red Hat host is missing a security update for krb5-appl.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0920 advisory.

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 While these have been replaced by tools such as OpenSSH in most environments, they remain in use in others.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)

Red Hat would like to thank the MIT Kerberos project for reporting this issue. Upstream acknowledges Tim Zingelman as the original reporter.

All krb5-appl users should upgrade to these updated packages, which contain a backported patch to correct this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 RHEL krb5-appl package based on the guidance in RHSA-2011:0920.
