medium Nessus Plugin ID 68302

Language:

Synopsis

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

Description

From Red Hat Security Advisory 2011:0920 :

Updated krb5-appl packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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 While these have been replaced by tools such as OpenSSH in most environments, they remain in use in others.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

Solution

Update the affected krb5-appl packages.
