Package: cifs-utils Version: 2:4.5-2+squeeze1 Severity: important
File with the size around 300MB was copied to the cifs filesystem mounted over openvpn connection using "cp" command. Command succeded, cp returns no error, but the file was broken. Size was exactly as original, but some bzip2 blocks were changed. Log inspection shows that there were errors during copying.
