Linux kernel <= 2.2.18 ptrace/execve Race Condition Vulnerability (1)

No description provided by source. source: http://www.securityfocus.com/bid/2529/info The Linux kernel is the core of all distributions of the Linux Operating System. It was originally written by Linus Torvalds, and is maintained by a community of developers. A problem in the Linux Kernel could...

CVE-2014-3125

Xen 4.4.x, when running on an ARM system, does not properly context switch the CNTKCTLEL1 register, which allows local guest users to modify the hardware timers and cause a denial of service crash via unspecified vectors...

CVE-2014-3125

CVE-2014-3125 concerns Xen 4.4.x on ARM where CNTKCTL_EL1 register is not properly context switched. This allows a local guest to modify hardware timers and, per the XSA-91 advisory, may enable a guest kernel to reconfigure timer interrupts for the entire system, potentially causing a denial of s...

kernel: local denial of service due to NT bit leakage

Linux kernel before 2.6.18, when running on x8664 systems, does not properly save or restore EFLAGS during a context switch, which allows local users to cause a denial of service crash by causing SYSENTER to set an NT flag, which can trigger a crash on the IRET of the next task...

CVE-2008-1778

CVE-2008-1778 : The vulnerability is described as an unspecified issue in the floating point context switch implementation on Sun Solaris 9/10 for x86, potentially allowing a local user to cause a denial of service (application exit), corrupt data, or trigger incorrect calculations via unknown ve...

CVE-2006-5755

Linux kernel before 2.6.18, when running on x8664 systems, does not properly save or restore EFLAGS during a context switch, which allows local users to cause a denial of service crash by causing SYSENTER to set an NT flag, which can trigger a crash on the IRET of the next task...

CVE-2006-5755

CVE-2006-5755 affects the Linux kernel on x86_64 where, during a context switch, EFLAGS were not properly saved/restored. This can allow a local user to trigger a denial-of-service crash by causing SYSENTER to set an NT flag, which may crash on the IRET of the next task. The vulnerability is docu...
