OracleVM 2.1 : kernel (OVMSA-2009-0017)
High Nessus Plugin ID 79461
Synopsis
The remote OracleVM host is missing one or more security updates.
Description
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 2.6.23.10 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)
Solution
Update the affected packages.
