Security fixes:
* the possibility of a timeout value overflow was found in the Linux kernel
high-resolution timers functionality, hrtimers. This could allow a local,
unprivileged user to execute arbitrary code, or cause a denial of service
(kernel panic). (CVE-2007-5966, Important)
* a flaw was found in the Intel PRO/1000 network driver in the Linux
kernel. Frames with sizes near the MTU of an interface may be split across
multiple hardware receive descriptors. Receipt of such a frame could leak
through a validation check, leading to a corruption of the length check. A
remote attacker could use this flaw to send a specially-crafted packet that
would cause a denial of service or code execution. (CVE-2009-1385,
Important)
* Michael Tokarev reported a flaw in the Realtek r8169 Ethernet driver in
the Linux kernel. This driver allowed interfaces using this driver to
receive frames larger than could be handled, which could lead to a remote
denial of service or code execution. (CVE-2009-1389, Important)
* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a
setuid or setgid program was executed. A local, unprivileged user could use
this flaw to bypass the mmap_min_addr protection mechanism and perform a
NULL pointer dereference attack, or bypass the Address Space Layout
Randomization (ASLR) security feature. (CVE-2009-1895, Important)
* Ramon de Carvalho Valle reported two flaws in the Linux kernel eCryptfs
implementation. A local attacker with permissions to perform an eCryptfs
mount could modify the metadata of the files in that eCrypfts mount to
cause a buffer overflow, leading to a denial of service or privilege
escalation. (CVE-2009-2406, CVE-2009-2407, Important)
* Konstantin Khlebnikov discovered a race condition in the ptrace
implementation in the Linux kernel. This race condition can occur when the
process tracing and the process being traced participate in a core dump. A
local, unprivileged user could use this flaw to trigger a deadlock,
resulting in a partial denial of service. (CVE-2009-1388, Moderate)
Bug fixes:
* possible host (dom0) crash when installing a Xen para-virtualized guest
while another para-virtualized guest was rebooting. (BZ#497812)
* no audit record for a directory removal if the directory and its subtree
were recursively watched by an audit rule. (BZ#507561)
* running 'echo 1 > /proc/sys/vm/drop_caches' on systems under high memory
load could cause ...
