These updated packages fix the following bugs :
- the GNU libc stub resolver is a minimal resolver that
works with Domain Name System (DNS) servers to satisfy
requests from applications for names. The GNU libc stub
resolver did not specify a source UDP port, and
therefore used predictable port numbers. This could have
make DNS spoofing attacks easier.
The Linux kernel has been updated to implement random UDP source ports
where none are specified by an application. This allows applications,
such as those using the GNU libc stub resolver, to use random UDP
source ports, helping to make DNS spoofing attacks harder.
- A set of patches detailed as 'sys_times: Fix system
unresponsiveness during many concurrent invocation of
sys_times()' and 'Minor code cleanup to sys_times()
call' introduced regression which caused a kernel panic
under high load. These patches were reverted in the
- A process could hang in an uninterruptible state while
accessing application data files due to race condition
in asynchronous direct I/O system calls.
- USB devices would not be detected on a PowerEdge R805
system. USB devices are now able to be detected on the
aforementioned system with this update.
Further, these updated packages add the following enhancement :
- Added HDMI support for AMD ATI chipsets RS780, RV610,
RV620, RV630, RV635, RV670 and RV770.
