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.

Security readout for executives and security teams

CVE-2004-0949 affects the legacy Linux smbfs client code in kernel 2.4 and 2.6. A malicious SMB/Samba server could send malformed fragmented responses that make a vulnerable client expose kernel information or mishandle internal counters. Exposure is most likely on legacy Linux systems running 2.4 or 2.6 kernels that use smbfs to connect to SMB/Samba shares, especially untrusted or attacker-controlled servers. The bundle does not identify modern kernels or cifs as affected. Treat this as a legacy-platform risk. It is unlikely to affect current supported Linux builds, but any remaining old systems using smbfs deserve prompt isolation, update, or retirement because the flaw touches kernel memory exposure. Mitigation focus: Apply relevant vendor kernel security updates for affected Linux distributions.; Retire unsupported Linux 2.4 and 2.6 systems where possible.; Avoid using smbfs with untrusted SMB/Samba servers until patched..
