Detailed vulnerability description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The smb_recv_trans2 function call in the samba filesystem (smbfs) in Linux kernel 2.4 and 2.6 does not properly handle the re-assembly of fragmented packets correctly, which could allow remote samba servers to (1) read arbitrary kernel information or (2) raise a counter value to an arbitrary number by sending the first part of the fragmented packet multiple times.


How to mitigate CVE-2004-0949

Install update from vendor's repository.
