Bugzilla: 608583: CVE-2010-2248 kernel: cifs: Fix a kernel BUG with remote OS/2 server
IAVA: 2011-A-0066


The MITRE CVE dictionary describes this issue as:

fs/cifs/cifssmb.c in the CIFS implementation in the Linux kernel before 2.6.34-rc4 allows remote attackers to cause a denial of service (panic) via an SMB response packet with an invalid CountHigh value, as demonstrated by a response from an OS/2 server, related to the CIFSSMBWrite and CIFSSMBWrite2 functions.

This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3 as it did not have support for CIFS. Future updates in Red Hat Enterprise Linux 4, 5, and Red Hat Enterprise MRG may address this flaw.
