CVE-2010-2248
Published: 7 September 2010
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.
From the Ubuntu Security Team
Suresh Jayaraman discovered that CIFS did not correctly validate certain response packats. A remote attacker could send specially crafted traffic that would crash the system, leading to a denial of service.
