Ubuntu 9.10 / 10.04 LTS / 10.10 : linux, linux-ec2 vulnerabilities (USN-1041-1)

high Nessus Plugin ID 51453

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Ben Hawkes discovered that the Linux kernel did not correctly filter registers on 64bit kernels when performing 32bit system calls. On a 64bit system, a local attacker could manipulate 32bit system calls to gain root privileges. (CVE-2010-3301)

Dan Rosenberg discovered that the btrfs filesystem did not correctly validate permissions when using the clone function. A local attacker could overwrite the contents of file handles that were opened for append-only, or potentially read arbitrary contents, leading to a loss of privacy. (CVE-2010-2537, CVE-2010-2538)

Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. A remote attacker could exploit this to read or write disk blocks that had changed file assignment or had become unlinked, leading to a loss of privacy.
(CVE-2010-2943)

Kees Cook discovered that the Intel i915 graphics driver did not correctly validate memory regions. A local attacker with access to the video card could read and write arbitrary kernel memory to gain root privileges. (CVE-2010-2962)

Robert Swiecki discovered that ftrace did not correctly handle mutexes. A local attacker could exploit this to crash the kernel, leading to a denial of service. (CVE-2010-3079)

Dan Rosenberg discovered that several network ioctls did not clear kernel memory correctly. A local user could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-3296, CVE-2010-3297, CVE-2010-3298)

It was discovered that KVM did not correctly initialize certain CPU registers. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-3698)

Brad Spengler discovered that stack memory for new a process was not correctly calculated. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-3858)

Kees Cook discovered that the ethtool interface did not correctly clear kernel memory. A local attacker could read kernel heap memory, leading to a loss of privacy. (CVE-2010-3861)

Kees Cook and Vasiliy Kulikov discovered that the shm interface did not clear kernel memory correctly. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-4072)

Dan Rosenberg discovered that the RME Hammerfall DSP audio interface driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4080, CVE-2010-4081)

James Bottomley discovered that the ICP vortex storage array controller driver did not validate certain sizes. A local attacker on a 64bit system could exploit this to crash the kernel, leading to a denial of service. (CVE-2010-4157)

Alan Cox discovered that the HCI UART driver did not correctly check if a write operation was available. If the mmap_min-addr sysctl was changed from the Ubuntu default to a value of 0, a local attacker could exploit this flaw to gain root privileges. (CVE-2010-4242)

Kees Cook discovered that some ethtool functions did not correctly clear heap memory. A local attacker with CAP_NET_ADMIN privileges could exploit this to read portions of kernel heap memory, leading to a loss of privacy. (CVE-2010-4655).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
