OracleVM 2.1 : kernel (OVMSA-2009-0017)


The remote OracleVM system is missing necessary patches to address critical security updates : CVE-2009-1895 The personality subsystem in the Linux kernel before 2.6.31-rc3 has a PER_CLEAR_ON_SETID setting that does not clear the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags when executing a setuid or setgid program, which makes it easier for local users to leverage the details of memory usage to (1) conduct NULL pointer dereference attacks, (2) bypass the mmap_min_addr protection mechanism, or (3) defeat address space layout randomization (ASLR). CVE-2007-5966 Integer overflow in the hrtimer_start function in kernel/hrtimer.c in the Linux kernel before allows local users to execute arbitrary code or cause a denial of service (panic) via a large relative timeout value. NOTE: some of these details are obtained from third party information. CVE-2009-1389 Buffer overflow in the RTL8169 NIC driver (drivers/net/r8169.c) in the Linux kernel before 2.6.30 allows remote attackers to cause a denial of service (kernel memory corruption and crash) via a long packet. - [misc] personality handling: fix PER_CLEAR_ON_SETID (Vitaly Mayatskikh) [511173 508842] (CVE-2009-1895) - [misc] hrtimer: fix a soft lockup (Amerigo Wang) [418061 418071] (CVE-2007-5966) - [net] r8169: fix crash when large packets are received (Ivan Vecera) [504731 504732] (CVE-2009-1389)
