Check for the version of the krb packages Detailed Explanation for this Vulnerability Assessment Updated packages fix a vulnerability found in the Kerberos FTP client distributed with the Red Hat Linux Advanced Server krb5 packages. [Updated 06 Feb 2003] Added fixed packages for Advanced Workstation 2.1. For Advanced Workstation 2.1 these packages also fix CVE-2002-1235 as described in RHSA-2002:250 Kerberos is a network authentication system. A problem has been found in the Kerberos FTP client. When retrieving a file with a name beginning with a pipe character, the FTP client will pass the file name to the command shell in a system() call. This could permit a malicious FTP server to write to files outside of the current directory or execute commands as the user running the FTP client. The Kerberos FTP client runs as the default FTP client when the Kerberos package krb5-workstation is installed on a Red Hat Linux Advanced Server distribution. All users of Kerberos are advised to upgrade to these errata packages which contain a backported patch and are not vulnerable to this issue.
