Linux kernel

[ MDVSA-2009:118 ] kernel

 Problem Description:

 Some vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 The clone system call in the Linux kernel 2.6.28 and earlier allows
 local users to send arbitrary signals to a parent process from an
 unprivileged child process by launching an additional child process
 with the CLONE_PARENT flag, and then letting this new process
 exit. (CVE-2009-0028)
 

[ MDVSA-2009:289 ] kernel

 Problem Description:

 Some vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 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

[ MDVSA-2010:257 ] kernel

 Problem Description:

 A vulnerability was discovered and corrected in the Linux 2.6 kernel:
 
 The setup_arg_pages function in fs/exec.c in the Linux kernel before
 2.6.36, when CONFIG_STACK_GROWSDOWN is used, does not properly restrict
 the stack memory consumption of the (1) arguments and (2) environment
 for a 32-bit application on a 64-bit platform, which allows local
 users to cause a denial of service (system crash) via a crafted exec
 system call, a related issue to CVE-2010-2240. (CVE-2010-3858)

[ MDVSA-2009:119 ] kernel

 Problem Description:

 Some vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 The exit_notify function in kernel/exit.c in the Linux kernel
 before 2.6.30-rc1 does not restrict exit signals when the
 CAP_KILL capability is held, which allows local users to send an
 arbitrary signal to a process by running a program that modifies the
 exit_signal field and then uses an exec system call to launch a setuid
 application. (CVE-2009-1337)

[ MDVSA-2010:034-2 ] kernel

 Some vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 Array index error in the gdth_read_event function in
 drivers/scsi/gdth.c in the Linux kernel before 2.6.32-rc8 allows
 local users to cause a denial of service or possibly gain privileges
 via a negative event index in an IOCTL request. (CVE-2009-3080)
 
 The collect_rx_frame function in drivers/isdn/hisax/hfc_usb.c in the
 Linux kernel before 2.6.32-rc7 allows attackers to have an unspecified

 ioctl struct in which iocts is not null terminated, which trigger a
 buffer overflow (CVE-2007-6151).

VMware Emulation Flaw x64 Guest Privilege Escalation (2/2)

By exploiting either of the VMware flaws described in this document,
user-mode code executing in a virtual machine may gain kernel
privileges within the virtual machine, dependent upon the guest
operating system.  The flaws have been proven exploitable on x64
versions of Windows, and they have produced potentially exploitable
crashes on x64 versions of *BSD.  The Linux kernel does not allow
exploitation of these flaws on x64 versions of Linux.

[ MDVSA-2010:247 ] kernel

 Problem Description:

 A vulnerability was discovered and corrected in the Linux 2.6 kernel:
 
 The compat_alloc_user_space functions in include/asm/compat.h files
 in the Linux kernel before 2.6.36-rc4-git2 on 64-bit platforms do
 not properly allocate the userspace memory required for the 32-bit
 compatibility layer, which allows local users to gain privileges by
 leveraging the ability of the compat_mc_getsockopt function (aka the

 related to a stack pointer underflow issue, as exploited in the wild

 The error-reporting functionality in (1) fs/ext2/dir.c, (2)

 mounting a filesystem that has corrupted dir->i_size and dir->i_blocks
 values and performing (a) read or (b) write operations. NOTE:

Please don't inundate me with e-mail because none of you bothered to read the exploit header.

The exploit so far has a 100% success rate on the systems it was designed to work on.
