CVE-2016-9377

Summary: CVE-2016-9377 affects Xen 4.5.x through 4.7.x on AMD systems without NRip. When Xen emulates instructions that generate software interrupts, an IDT entry miscalculation can allow a local HVM guest OS user to crash the guest (DoS). The issue arises from incorrect handling of IDT formats d...

x86 software interrupt injection mis-handled

ISSUE DESCRIPTION There are two closely-related bugs. When Xen emulates instructions which generate software interrupts it needs to perform a privilege check involving an IDT lookup. This check is sometimes erroneously conducted as if the IDT had the format for a 32-bit guest, when in fact it is ...

Linux Kernel ptrace/sysret Local Privilege Escalation

/ CVE-2014-4699 ptrace/sysret PoC by Vitaly Nikolenko [email protected] gcc -O2 pocv0.c This code is kernel specific. On Ubuntu 12.04.0 LTS 3.2.0-23-generic, the following will trigger the GP in sysret and overwrite the PF handler so we can land to our NOP sled mapped at 0x80000000. However, onc...

Linux Kernel ptrace/sysret - Local Privilege Escalation Exploit

The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service double...

CVE-2007-1194

Norman SandBox Analyzer does not use the proper range for Interrupt Descriptor Table IDT entries, which allows local users to determine that the local machine is an emulator, or a similar environment not based on a physical Intel processor, which allows attackers to produce malware that is more...

CVE-2007-1194

CVE-2007-1194 concerns Norman SandBox Analyzer and its improper IDT entry range handling. The vulnerability allows local users to determine whether the local machine is running in an emulator or a non-physical Intel-based environment, enabling malware that is harder to analyze to tailor its behav...
