Description Matt Fleming (RETIRED) gentoo-dev 2007-08-12 20:55:45 UTC
A weakness has been reported in the Linux Kernel, which potentially can be exploited by malicious people to bypass certain security restrictions.

The weakness is caused due to the Linux Kernel not correctly enforcing the defined signing options when mounting a CIFS file system. This may weaken the security and can be leveraged to perform further attacks.

The weakness is fixed in version 2.6.23-rc1.
