The data between the new file size and the old file size was not discarded and the number of bytes used by the inode were not correctly decremented, which gave the wrong report for callers of the stat(2) syscall. This wasted metadata space and allowed for the truncated data to be leaked, and data corruption or loss to occur. A caller of the clone ioctl could exploit this flaw by using only standard file-system operations without root access to read the truncated data.(CVE-2015-8374) - A flaw was found in the Linux kernel last seen 2020-03-17 modified 2019-05-13 plugin id 124813 published 2019-05-13 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/124813 title EulerOS Virtualization 3.0.1.0 : kernel (EulerOS-SA-2019-1489) NASL family Scientific Linux Local Security Checks NASL id SL_20160510_KERNEL_ON_SL6_X.NASL description Security Fix(es) : - It was found that reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service.

(CVE-2015-8543) last seen 2020-06-01 modified 2020-06-02 plugin id 92679 published 2016-08-02 reporter This script is Copyright (C) 2016-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/92679 title Debian DSA-3426-1 : Linux Security Update NASL family Debian Local Security Checks NASL id DEBIAN_DSA-3434.NASL description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. - CVE-2015-7513 It was discovered that a local user permitted to use the x86 KVM subsystem could configure the PIT emulation to cause a denial of service (crash). - CVE-2015-7550 Dmitry Vyukov discovered a race condition in the keyring subsystem that allows a local user to cause a denial of service (crash). - CVE-2015-8543 It was discovered that a local user permitted to create raw sockets could cause a denial-of-service by specifying an invalid protocol number for the socket. The attacker must have the CAP_NET_RAW capability. - CVE-2015-8550 Felix Wilhelm of ERNW discovered that the Xen PV backend drivers may read critical data from shared memory multiple times. This flaw can be used by a guest kernel to cause a denial of service (crash) on the host, or possibly for privilege escalation. - CVE-2015-8551 / CVE-2015-8552 Konrad Rzeszutek Wilk of Oracle discovered that the Xen PCI backend driver does not adequately validate the device state when a guest configures MSIs. This flaw can be used by a guest kernel to cause a denial of service (crash or disk space exhaustion) on the host. - CVE-2015-8569 Dmitry Vyukov discovered a flaw in the PPTP sockets implementation that leads to an information leak to local users. - CVE-2015-8575 David Miller discovered a flaw in the Bluetooth SCO sockets implementation that leads to an information leak to local users. - CVE-2015-8709 Jann Horn discovered a flaw in the permission checks for use of the ptrace feature. A local user who has the CAP_SYS_PTRACE capability within their own user namespace could use this flaw for privilege escalation if a more privileged process ever enters that user namespace. This affects at least the LXC system. In addition, this update fixes some regressions in the previous update : - #808293 A regression in the UDP implementation prevented freeradius and some other applications from receiving data. - #808602 / #808953 A regression in the USB XHCI driver prevented use of some devices in USB 3 SuperSpeed ports. - #808973 A fix to the radeon driver interacted with an existing bug to cause a crash at boot when using some AMD/ATI graphics cards. This issue only affects wheezy. last seen 2020-06-01 modified 2020-06-02 plugin id 87741 published 2016-01-06 reporter This script is Copyright (C) 2016-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/87741 title Debian DSA-3434-1 : linux - security update
