Description:
Some vulnerabilities have been reported in the Linux kernel, which can be exploited by malicious people to cause a DoS (Denial of Service), and by malicious, local users to cause a DoS or to potentially gain escalated privileges.
1) A race condition error exists in the dnotify subsystem between calls to "fcntl()" and "close()". This can be exploited to cause a system crash or potentially gain root privileges.
2) A boundary error in the Tehuti network driver can be exploited to corrupt kernel memory via specially crafted "BDX_OP_WRITE" IOCTL calls.
The vulnerabilities are reported in versions prior to 2.6.25.1.
3) An error exists in the implementation of the IPsec protocol. This can be exploited to crash an affected system via fragmented ESP packets.
Successful exploitation of the vulnerability requires the ability to manipulate network packets sent from an authenticated IPsec peer.
This vulnerability is reported in versions prior to 2.6.25.
