CIFS signing sec= mount options don't work correctly

The Linux kernel before 2.6.23-rc1 checks the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request...

[SECURITY] Fedora 7 Update: samba-3.0.26a-0.fc7

Samba is the suite of programs by which a lot of PC-related machines share files, printers, and other information such as lists of available files and printers. The Windows NT, OS/2, and Linux operating systems support this natively, and add-on packages can enable the same thing for DOS, Windows,...
