kernel: x86-64: avoid sysret to non-canonical address
It was found that the Xen hypervisor implementation as shipped with Red Hat Enterprise Linux 5 did not properly restrict the syscall return addresses in the sysret return path to canonical addresses. An unprivileged user in a 64-bit para-virtualized guest, that is running on a 64-bit host that ha...
freetype: incorrect type cast allowing input sanity check bypass in ft_smooth_render_generic() (#35604)
FreeType before 2.4.9, as used in Mozilla Firefox Mobile before 10.0.4 and other products, on 64-bit platforms allows remote attackers to cause a denial of service invalid heap read operation and memory corruption or possibly execute arbitrary code via vectors related to the cell table of a font...
kernel: oom_badness() integer overflow
Integer overflow in the oombadness function in mm/oomkill.c in the Linux kernel before 3.1.8 on 64-bit platforms allows local users to cause a denial of service memory consumption or process termination by using a certain large amount of memory...
ghostscript: CWD included in the default library search path
Untrusted search path vulnerability in Ghostscript 8.62 allows local users to execute arbitrary PostScript code via a Trojan horse Postscript library file in Encoding/ under the current working directory, a different vulnerability than CVE-2010-2055...
ruby: memory corruption in BigDecimal on 64bit platforms
The VpMemAlloc function in bigdecimal.c in the BigDecimal class in Ruby 1.9.2-p136 and earlier, as used on Apple Mac OS X before 10.6.7 and other platforms, does not properly allocate memory, which allows context-dependent attackers to execute arbitrary code or cause a denial of service applicati...
CVE-2011-1705
Heap-based buffer overflow in nipplib.dll in Novell iPrint Client before 5.64 allows remote attackers to execute arbitrary code via a crafted client-file-name parameter in a printer-url...
kernel: setup_arg_pages: diagnose excessive argument size
The setupargpages function in fs/exec.c in the Linux kernel before 2.6.36, when CONFIGSTACKGROWSDOWN 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...
Host crash due to failure to correctly validate PV kernel execution state
ISSUE DESCRIPTION Cannot specify user mode execution without specifying user-mode pagetables. Failure to validate this allows a malicious or buggy 64 bit PV guest to crash the host. nb: predates vulnerability handling process and therefore no formal announcement...
kernel: setup_arg_pages: diagnose excessive argument size
The setupargpages function in fs/exec.c in the Linux kernel before 2.6.36, when CONFIGSTACKGROWSDOWN 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...
kernel: gdth: integer overflow in ioc_general()
Integer overflow in the iocgeneral function in drivers/scsi/gdth.c in the Linux kernel before 2.6.36.1 on 64-bit platforms allows local users to cause a denial of service memory corruption or possibly have unspecified other impact via a large argument in an ioctl call...

kernel: wireless: fix 64K kernel heap content leak via ioctl
The cfg80211wextgiwessid function in net/wireless/wext-compat.c in the Linux kernel before 2.6.36-rc3-next-20100831 does not properly initialize certain structure members, which allows local users to leverage an off-by-one error in the ioctlstandardiwpoint function in net/wireless/wext-core.c, an...
kernel: 64-bit Compatibility Mode Stack Pointer Underflow
The compatallocuserspace 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...
