CVE-2006-5173

Linux kernel does not properly save or restore EFLAGS during a context switch, or reset the flags when creating new threads, which allows local users to cause a denial of service process crash, as demonstrated using a process that sets the Alignment Check flag EFLAGS 0x40000, which triggers a...

DEBIAN-CVE-2015-4164

The compatiret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service large loop and system hang via a hypercalliret call with EFLAGS.VM set...

Debian DSA-2662-1 : xen - several vulnerabilities

Multiple vulnerabilities have been discovered in the Xen hypervisor. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2013-1917 The SYSENTER instruction can be used by PV guests to accelerate system call processing. This instruction, however, leaves the...

Xen PV DoS vulnerability with SYSENTER

ISSUE DESCRIPTION The SYSENTER instruction can be used by PV guests to accelerate system call processing. This instruction, however, leaves the EFLAGS register mostly unmodified - in particular, the NT flag doesn't get cleared. If the hypervisor subsequently uses IRET to return to the guest which...

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...

Mandrake Linux Security Advisory : kernel (MDKSA-2007:171)

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel : The Linux kernel did not properly save or restore EFLAGS during a context switch, or reset the flags when creating new threads, which allowed local users to cause a denial of service process crash CVE-2006-5755. The...

USN-416-1: Linux kernel vulnerabilities

Mark Dowd discovered that the netfilter iptables module did not correcly handle fragmented IPv6 packets. By sending specially crafted packets, a remote attacker could exploit this to bypass firewall rules. This has has already been fixed for Ubuntu 6.10 in USN-395-1; this is the corresponding fix...

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...

CVE-2006-5173

CVE-2006-5173 concerns the Linux kernel: local users can trigger a denial-of-service by mismanaging EFLAGS during context switches and thread creation (Alignment Check flag 0x40000), causing SIGBUS in other processes with unaligned accesses. Multiple connected sources confirm the issue and refere...

CVE-2004-0001

The CVE-2004-0001 issue is described across multiple advisories as a local privilege escalation in the AMD64 Linux kernel ptrace emulation, due to incorrect eflags handling in 32-bit ptrace. Affected: AMD64 Linux kernels; root cause: eflags processing in the ptrace emulation path; impact: local u...

CVE-2002-1319

The CVE-2002-1319 issue affects the Linux kernel on x86, specifically versions 2.4.20 and earlier and 2.5.x. The root cause is a flaw in emulation mode where TF and NT EFLAGS are not properly cleared, enabling a local user to cause a denial of service (hang). The impact is a local DoS without rem...
