Red Hat Bugzilla – Bug 82447
Security issue with krb5 ftp client
Last modified: 2007-11-30 17:06:52 EST
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
This issue will become public on Jan24
