CVE-2009-1633 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1633): Multiple buffer overflows in the cifs subsystem in the Linux kernel before 2.6.29.4 allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or (2) long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c.
I've just spent rather longer than I would have liked figuring out which patches to apply and in which order (with a view to backporting to the next 2.6.28-hardened release). The series is as follows: 27b87fe52baba0a55e9723030e76fce94fabcea4 968460ebd8006d55661dec0fb86712b40d71c413 7b0c8fcff47a885743125dd843db64af41af5a61 d37dc42ab6f040b8f0f2962ab219c5b2accf748d 66345f50f070ae7412a28543ee197cb5eff73598 7fabf0c9479fef9fdb9528a5fbdb1cb744a744a4 69f801fcaa03be83d58c564f00913b7c172808e4 066ce6899484d9026acd6ba3a8dbbedb33d7ae1b cc20c031bb067eb3280a1c4b5c42295093e24863 59140797c5817363087b0ffb46e6bb81a11fe0dc 460b96960d1946914e50316ffeefe7b41dddce91 f58841666bc22e827ca0dcef7b71c7bc2758ce82 20418acd6874792359b42c12d159f42f17593f34 d185cda7712fd1d9e349174639d76eadc66679be 9e39b0ae8af46c83b85dae7ff5251911a80fce5a 18295796a30cada84e933d805072dc2248d54f98 2edd6c5b0517b9131ede9e74cb121898ccd73042 341060273232a2df0d1a7fa53abc661fcf22747c afe48c31ea5c74eaac58621ce1c85ae8187c4383 d8e2f53ac99f4ce7d63807a84f98d1b80df598cf By applying these patches, bug 266638 (CVE-2009-1439) is also closed, and it is *not* necessary (or even possible) to apply the following patches: 5b0ecf297e133be1e4767b1e446a6d7902274c13 a7a7d2fe8813c3bee7d7db9ba889fc2c2dd39dd7
