Secunia Security Advisory - Ubuntu has issued an update for the kernel. This fixes some weaknesses, security issues, and vulnerabilities, which can be exploited by malicious, local users to disclose system and potentially sensitive information, conduct spoofing attacks, bypass certain security restrictions, cause a DoS (Denial of Service), and gain escalated privileges, and by malicious people to cause a DoS and potentially compromise a vulnerable system.

DESCRIPTION:
Ubuntu has issued an update for the kernel. This fixes some
weaknesses, security issues, and vulnerabilities, which can be
exploited by malicious, local users to disclose system and
potentially sensitive information, conduct spoofing attacks, bypass
certain security restrictions, cause a DoS (Denial of Service), and
gain escalated privileges, and by malicious people to cause a DoS and
potentially compromise a vulnerable system.

1) Errors within the implementation of the External Data
Representation (XDR) for NFSv4 can be exploited to cause a kernel
panic and potentially execute arbitrary code by sending specially
crafted compound requests to the NFSv4 server.
2) An error within the GFS2 file system when handing certain rename
operations can be exploited to cause a kernel crash.
3) An error within the SCTP implementation can be exploited to cause
a crash by sending specially crafted network traffic.
4) An error within the SCTP implementation when handling HMAC
calculations can be exploited to cause a crash by sending specially
crafted network traffic.
5) An error within the RDS implementation can be exploited to execute
arbitrary code with kernel privileges.
