The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update addresses the following security issues:
a memory leak in keyctl handling. A local user could use this flaw to
deplete kernel memory, eventually leading to a denial of service.
(CVE-2009-0031, Important)
a buffer overflow in the Linux kernel Partial Reliable Stream Control
Transmission Protocol (PR-SCTP) implementation. This could, potentially,
lead to a denial of service if a Forward-TSN chunk is received with a large
stream ID. (CVE-2009-0065, Important)
a flaw when handling heavy network traffic on an SMP system with many
cores. An attacker who could send a large amount of network traffic could
create a denial of service. (CVE-2008-5713, Important)
the code for the HFS and HFS Plus (HFS+) file systems failed to properly
handle corrupted data structures. This could, potentially, lead to a local
denial of service. (CVE-2008-4933, CVE-2008-5025, Low)
a flaw was found in the HFS Plus (HFS+) file system implementation. This
could, potentially, lead to a local denial of service when write operations
are performed. (CVE-2008-4934, Low)
In addition, these updated packages fix the following bugs:
when using the nfsd daemon in a clustered setup, kernel panics appeared
seemingly at random. These panics were caused by a race condition in
the device-mapper mirror target.
the clock_gettime(CLOCK_THREAD_CPUTIME_ID, ) syscall returned a smaller
timespec value than the result of previous clock_gettime() function
execution, which resulted in a negative, and nonsensical, elapsed time value.
nfs_create_rpc_client was called with a “flavor” parameter which was
usually ignored and ended up unconditionally creating the RPC client with
an AUTH_UNIX flavor. This caused problems on AUTH_GSS mounts when the
credentials needed to be refreshed. The credops did not match the
authorization type, which resulted in the credops dereferencing an
incorrect part of the AUTH_UNIX rpc_auth struct.
when copy_user_c terminated prematurely due to reading beyond the end of
the user buffer and the kernel jumped to the exception table entry, the rsi
register was not cleared. This resulted in exiting back to user code with
garbage in the rsi register.
the hexdump data in s390dbf traces was incomplete. The length of the data
traced was incorrect and the SAN payload was read from a different place
then it was written to.
when using connected mode (CM) in IPoIB on ehca2 hardware, it was not
possible to transmit any data.
when an application called fork() and pthread_create() many times and, at
some point, a thread forked a child and then attempted to call the
setpgid() function, then this function failed and returned and ESRCH error
value.
Users should upgrade to these updated packages, which contain backported
patches to correct these issues. Note: for this update to take effect, the
system must be rebooted.
