A problem has been found in the Kerberos ftp client. When retrieving a file with a filename beginning with a pipe character, the ftp client will pass the filename to the command shell in a system() call. This could allow 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. This issue will become public on Jan24
