UNKNOWN Summary
The em_syscall function in arch/x86/kvm/emulate.c in the KVM implementation in the Linux kernel before 3.2.14 does not properly handle the 0f05 (aka syscall) opcode, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application, as demonstrated by an NASM file.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-4307 Nageswara R Sastry reported an issue in the ext4 filesystem. Local users with the privileges to mount a filesystem can cause a denial of service (BUG) by providing a s_log_groups_per_flex value greater than 31. - CVE-2011-1833 Vasiliy Kulikov of Openwall and Dan Rosenberg discovered an information leak in the eCryptfs filesystem. Local users were able to mount arbitrary directories. - CVE-2011-4347 Sasha Levin reported an issue in the device assignment functionality in KVM. Local users with permission to access /dev/kvm could assign unused pci devices to a guest and cause a denial of service (crash). - CVE-2012-0045 Stephan Barwolf reported an issue in KVM. Local users in a 32-bit guest running on a 64-bit system can crash the guest with a syscall instruction. - CVE-2012-1090 CAI Qian reported an issue in the CIFS filesystem. A reference count leak can occur during the lookup of special files, resulting in a denial of service (oops) on umount. - CVE-2012-1097 H. Peter Anvin reported an issue in the regset infrastructure. Local users can cause a denial of service (NULL pointer dereference) by triggering the write methods of readonly regsets. last seen 2020-03-17 modified 2012-03-27 plugin id 58486 published 2012-03-27 reporter This script is Copyright (C) 2012-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/58486 title Debian DSA-2443-1 : linux-2.6 - privilege escalation/denial of service NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2012-2003.NASL description Description of changes: * CVE-2012-0207: Denial of service bug in IGMP.
