Detail
Problem Description: An updated vsftpd package that fixes a security issue and various bugs is now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 3. Description: vsftpd (Very Secure File Transfer Protocol (FTP) daemon) is a secure FTP server for Linux and Unix-like systems. The version of vsftpd as shipped in Red Hat Enterprise Linux 4 when used in combination with Pluggable Authentication Modules (PAM) had a memory leak on an invalid authentication attempt. Since vsftpd prior to version 2.0.5 allows any number of invalid attempts on the same connection this memory leak could lead to an eventual DoS. (CVE-2008-2375) This update mitigates this security issue by including a backported patch which terminates a session after a given number of failed log in attempts. The default number of attempts is 3 and this can be configured using the "max_login_fails" directive. This package also addresses the following bugs: * when uploading unique files, a bug in vsftpd caused the file to be saved with a suffix '.1' even when no previous file with that name existed. This issues is resolved in this package. * when vsftpd was run through the init script, it was possible for the init script to print an 'OK' message, even though the vsftpd may not have started. The init script no longer produces a false verification with this update. * vsftpd only supported usernames with a maximum length of 32 characters. The updated package now supports usernames up to 128 characters long. * a system flaw meant vsftpd output could become dependent on the timing or sequence of other events, even when the "lock_upload_files" option was set. If a file, filename.ext, was being uploaded and a second transfer of the file, filename.ext, was started before the first transfer was finished, the resultant uploaded file was a corrupt concatenation of the latter upload and the tail of the earlier upload. With this updated package, vsftpd allows the earlier upload to complete before overwriting with the latter upload, fixing the issue. * the 'lock_upload_files' option was not documented in the manual page. A new manual page describing this option is included in this package. * vsftpd did not support usernames that started with an underscore or a period character. These special characters are now allowed at the beginning of a username. * when storing a unique file, vsftpd could cause an error for some clients. This is rectified in this package. * vsftpd init script was found to not be Linux Standards Base compliant. This update corrects their exit codes to conform to the standard. All vsftpd users are advised to upgrade to this updated package, which resolves these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188 5. Bugs fixed (http://bugzilla.redhat.com/): 197141 - vsftpd 2.0.1 memory leak 206843 - vsftpd is checked wrongly in init script 236326 - maximum username length too short 240550 - vsftpd has a create/lock race condition which corrupts uploads 250727 - Uploaded file corrupted when two connections from same client uploading same file simultaneously 316381 - lock_upload_files not documented in vsftpd.conf man page 408431 - Memory leak in pattern matching function 431450 - Wrong init script 453376 - CVE-2008-2375 older vsftpd authentication memory leak |
