Description:
A vulnerability has been reported in the Linux Kernel, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
The vulnerability is caused due to the "SendReceive()" function in fs/cifs/transport.c assuming wrong buffer sizes. This can be exploited to cause a buffer overflow by sending specially crafted responses to a vulnerable system.
Successful exploitation may require that a malicious server is used to mount a CIFS share.
The vulnerability is reported in version 2.6.23. Other versions may also be affected.
Solution:
Fixed in the GIT repository.
