Security fixes :
several flaws were found in the way the Linux kernel CIFS implementation handles Unicode strings. CIFS clients convert Unicode strings sent by a server to their local character sets, and then write those strings into memory. If a malicious server sent a long enough string, it could write past the end of the target memory region and corrupt other memory areas, possibly leading to a denial of service or privilege escalation on the client mounting the CIFS share. (CVE-2009-1439, CVE-2009-1633, Important)
the Linux kernel Network File System daemon (nfsd) implementation did not drop the CAP_MKNOD capability when handling requests from local, unprivileged users.
This flaw could possibly lead to an information leak or privilege escalation. (CVE-2009-1072, Moderate)
Frank Filz reported the NFSv4 client was missing a file permission check for the execute bit in some situations.
This could allow local, unprivileged users to run non-executable files on NFSv4 mounted file systems.
(CVE-2009-1630, Moderate)
a missing check was found in the hypervisor_callback() function in the Linux kernel provided by the kernel-xen package. This could cause a denial of service of a 32-bit guest if an application running in that guest accesses a certain memory location in the kernel.
(CVE-2009-1758, Moderate)
a flaw was found in the AGPGART driver. The agp_generic_alloc_page() and agp_generic_alloc_pages() functions did not zero out the memory pages they allocate, which may later be available to user-space processes. This flaw could possibly lead to an information leak. (CVE-2009-1192, Low)
Bug fixes :
a race in the NFS client between destroying cached access rights and unmounting an NFS file system could have caused a system crash. ‘Busy inodes’ messages may have been logged. (BZ#498653)
nanosleep() could sleep several milliseconds less than the specified time on Intel Itanium®-based systems.
(BZ#500349)
LEDs for disk drives in AHCI mode may have displayed a fault state when there were no faults. (BZ#500120)
ptrace_do_wait() reported tasks were stopped each time the process doing the trace called wait(), instead of reporting it once. (BZ#486945)
epoll_wait() may have caused a system lockup and problems for applications. (BZ#497322)
missing capabilities could possibly allow users with an fsuid other than 0 to perform actions on some file system types that would otherwise be prevented.
(BZ#497271)
on NFS mounted file systems, heavy write loads may have blocked nfs_getattr() for long periods, causing commands that use stat(2), such as ls, to hang. (BZ#486926)
in rare circumstances, if an application performed multiple O_DIRECT reads per virtual memory page and also performed fork(2), the buffer storing the result of the I/O may have ended up with invalid data. (BZ#486921)
when using GFS2, gfs2_quotad may have entered an uninterpretable sleep state. (BZ#501742)
with this update, get_random_int() is more random and no longer uses a common seed value, reducing the possibility of predicting the values returned.
(BZ#499783)
the ‘-fwrapv’ flag was added to the gcc build options to prevent gcc from optimizing away wrapping. (BZ#501751)
a kernel panic when enabling and disabling iSCSI paths.
(BZ#502916)
using the Broadcom NetXtreme BCM5704 network device with the tg3 driver caused high system load and very bad performance. (BZ#502837)
‘/proc/[pid]/maps’ and ‘/proc/[pid]/smaps’ can only be read by processes able to use the ptrace() call on a given process; however, certain information from ‘/proc/[pid]/stat’ and ‘/proc/[pid]/wchan’ could be used to reconstruct memory maps. (BZ#499546)
