NONE Summary
Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Leveraging Race Conditions This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
- Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

(bsc#917830) - CVE-2014-9728: The UDF filesystem implementation in the Linux kernel before 3.18.2 did not validate certain lengths, which allowed local users to cause a denial of service (buffer over-read and system crash) via a crafted filesystem image, related to fs/udf/inode.c and fs/udf/symlink.c (bsc#933904). - CVE-2014-9730: The udf_pc_to_char function in fs/udf/symlink.c in the Linux kernel before 3.18.2 relies on component lengths that are unused, which allowed local users to cause a denial of service (system crash) via a crafted UDF filesystem image (bsc#933904). - CVE-2014-9729: The udf_read_inode function in fs/udf/inode.c in the Linux kernel before 3.18.2 did not ensure a certain data-structure size consistency, which allowed local users to cause a denial of service (system crash) via a crafted UDF filesystem image (bsc#933904). - CVE-2014-9731: The UDF filesystem implementation in the Linux kernel before 3.18.2 did not ensure that space is available for storing a symlink target's name along with a trailing \0 character, which allowed local users to obtain sensitive information via a crafted filesystem image, related to fs/udf/symlink.c and fs/udf/unicode.c (bsc#933896). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory.

NASL family SuSE Local Security Checks NASL id SUSE_SU-2015-1611-1.NASL description The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various security and bugfixes. Following security bugs were fixed : - CVE-2015-5707: An integer overflow in the SCSI generic driver could be potentially used by local attackers to crash the kernel or execute code (bsc#940338). - CVE-2015-5364: A remote denial of service (hang) via UDP flood with incorrect package checksums was fixed. (bsc#936831). - CVE-2015-5366: A remote denial of service (unexpected error returns) via UDP flood with incorrect package checksums was fixed. (bsc#936831). - CVE-2015-1420: A race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel allowed local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function (bnc#915517). - CVE-2015-4700: A local user could have created a bad instruction in the JIT processed BPF code, leading to a kernel crash (bnc#935705). - CVE-2015-4167: The UDF filesystem in the Linux kernel was vulnerable to a crash which could occur while fetching inode information from a corrupted/malicious udf file system image. (bsc#933907). - CVE-2014-9728 CVE-2014-9729 CVE-2014-9730 CVE-2014-9731: Various issues in handling UDF filesystems in the Linux kernel allowed the corruption of kernel memory and other issues. An attacker able to mount a corrupted/malicious UDF file system image could cause the kernel to crash. (bsc#933904 bsc#933896) - CVE-2015-2150: The Linux kernel did not properly restrict access to PCI command registers, which might have allowed local guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response (bsc#919463). - CVE-2015-0777: drivers/xen/usbback/usbback.c as used in the Linux kernel 2.6.x and 3.x in SUSE Linux distributions, allowed guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory via unspecified vectors (bnc#917830). - CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux kernel did not prevent the TS_COMPAT flag from reaching a user-mode task, which might have allowed local users to bypass the seccomp or audit protection mechanism via a crafted application that uses the (1) fork or (2) close system call, as demonstrated by an attack against seccomp before 3.16 (bnc#926240). - CVE-2015-1805: The Linux kernels implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (bsc#933429). Also The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 86121 published 2015-09-24 reporter This script is Copyright (C) 2015-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/86121 title SUSE SLED11 / SLES11 Security Update : kernel (SUSE-SU-2015:1611-1) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from SUSE update advisory SUSE-SU-2015:1611-1. # The text itself is copyright (C) SUSE. # include("compat.inc"); if (description) { script_id(86121); script_version("2.10"); script_cvs_date("Date: 2019/09/11 11:22:12"); script_cve_id("CVE-2014-9728", "CVE-2014-9729", "CVE-2014-9730", "CVE-2014-9731", "CVE-2015-0777", "CVE-2015-1420", "CVE-2015-1805", "CVE-2015-2150", "CVE-2015-2830", "CVE-2015-4167", "CVE-2015-4700", "CVE-2015-5364", "CVE-2015-5366", "CVE-2015-5707"); script_bugtraq_id(72357, 73014, 73699, 73921, 74951, 74963, 74964, 75001, 75356, 75510); script_name(english:"SUSE SLED11 / SLES11 Security Update : kernel (SUSE-SU-2015:1611-1)"); script_summary(english:"Checks rpm output for the updated packages."); script_set_attribute( attribute:"synopsis", value:"The remote SUSE host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various security and bugfixes.

A local user can use this flaw to exploit vulnerabilities in modules that would not normally be loaded. - CVE-2014-7822 Akira Fujita found that the splice() system call did not validate the given file offset and length. A local unprivileged user can use this flaw to cause filesystem corruption on ext4 filesystems, or possibly other effects. - CVE-2014-8160 Florian Westphal discovered that a netfilter (iptables/ip6tables) rule accepting packets to a specific SCTP, DCCP, GRE or UDPlite port/endpoint could result in incorrect connection tracking state. If only the generic connection tracking module (nf_conntrack) was loaded, and not the protocol-specific connection tracking module, this would allow access to any port/endpoint of the specified protocol. - CVE-2014-8559 It was found that kernel functions that iterate over a directory tree can dead-lock or live-lock in case some of the directory entries were recently deleted or dropped from the cache. A local unprivileged user can use this flaw for denial of service. - CVE-2014-9585 Andy Lutomirski discovered that address randomisation for the vDSO in 64-bit processes is extremely biased. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism. - CVE-2014-9683 Dmitry Chernenkov discovered that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding, resulting in local denial of service. - CVE-2015-0239 It was found that KVM did not correctly emulate the x86 SYSENTER instruction. An unprivileged user within a guest system that has not enabled SYSENTER, for example because the emulated CPU vendor is AMD, could potentially use this flaw to cause a denial of service or privilege escalation in that guest. - CVE-2015-1420 It was discovered that the open_by_handle_at() system call reads the handle size from user memory a second time after validating it. A local user with the CAP_DAC_READ_SEARCH capability could use this flaw for privilege escalation. - CVE-2015-1421 It was found that the SCTP implementation could free an authentication state while it was still in use, resulting in heap corruption. This could allow remote users to cause a denial of service or privilege escalation. - CVE-2015-1593 It was found that address randomisation for the initial stack in 64-bit processes was limited to 20 rather than 22 bits of entropy. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism. last seen 2020-03-17 modified 2015-02-24 plugin id 81449 published 2015-02-24 reporter This script is Copyright (C) 2015-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/81449 title Debian DSA-3170-1 : linux - security update NASL family SuSE Local Security Checks NASL id OPENSUSE-2016-124.NASL description The openSUSE 13.1 kernel was updated to receive various security and bugfixes.

Following security bugs were fixed : - CVE-2015-3290: A flaw was found in the way the Linux kernels nested NMI handler and espfix64 functionalities interacted during NMI processing. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. - CVE-2015-3212: A race condition flaw was found in the way the Linux kernels SCTP implementation handled Address Configuration lists when performing Address Configuration Change (ASCONF). A local attacker could use this flaw to crash the system via a race condition triggered by setting certain ASCONF options on a socket. - CVE-2015-5364: A remote denial of service (hang) via UDP flood with incorrect package checksums was fixed. (bsc#936831). - CVE-2015-5366: A remote denial of service (unexpected error returns) via UDP flood with incorrect package checksums was fixed. (bsc#936831). - CVE-2015-4700: A local user could have created a bad instruction in the JIT processed BPF code, leading to a kernel crash (bnc#935705). - CVE-2015-1420: Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel allowed local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function (bnc#915517). - CVE-2015-4692: The kvm_apic_has_events function in arch/x86/kvm/lapic.h in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging /dev/kvm access for an ioctl call (bnc#935542). - CVE-2015-4167 CVE-2014-9728 CVE-2014-9730 CVE-2014-9729 CVE-2014-9731: Various problems in the UDF filesystem were fixed that could lead to crashes when mounting prepared udf filesystems. - CVE-2015-4002: drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel did not ensure that certain length values are sufficiently large, which allowed remote attackers to cause a denial of service (system crash or large loop) or possibly execute arbitrary code via a crafted packet, related to the (1) oz_usb_rx and (2) oz_usb_handle_ep_data functions (bnc#933934). - CVE-2015-4003: The oz_usb_handle_ep_data function in drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel allowed remote attackers to cause a denial of service (divide-by-zero error and system crash) via a crafted packet (bnc#933934). - CVE-2015-4001: Integer signedness error in the oz_hcd_get_desc_cnf function in drivers/staging/ozwpan/ozhcd.c in the OZWPAN driver in the Linux kernel allowed remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted packet (bnc#933934). - CVE-2015-4036: A potential memory corruption in vhost/scsi was fixed. - CVE-2015-2922: The ndisc_router_discovery function in net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in the Linux kernel allowed remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message (bnc#922583). - CVE-2015-3636: It was found that the Linux kernels ping socket implementation did not properly handle socket unhashing during spurious disconnects, which could lead to a use-after-free flaw. On x86-64 architecture systems, a local user able to create ping sockets could use this flaw to crash the system. On non-x86-64 architecture systems, a local user able to create ping sockets could use this flaw to escalate their privileges on the system. - CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux kernel used an incorrect data type in a sysctl table, which allowed local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry (bnc#919007). - CVE-2015-3339: Race condition in the prepare_binprm function in fs/exec.c in the Linux kernel allowed local users to gain privileges by executing a setuid program at a time instant when a chown to root is in progress, and the ownership is changed but the setuid bit is not yet stripped. - CVE-2015-1465: The IPv4 implementation in the Linux kernel did not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allowed remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets (bnc#916225). The following non-security bugs were fixed : - ALSA: ak411x: Fix stall in work callback (boo#934755). - ALSA: emu10k1: Emu10k2 32 bit DMA mode (boo#934755). - ALSA: emu10k1: Fix card shortname string buffer overflow (boo#934755). - ALSA: emu10k1: do not deadlock in proc-functions (boo#934755). - ALSA: emux: Fix mutex deadlock at unloading (boo#934755). - ALSA: emux: Fix mutex deadlock in OSS emulation (boo#934755). - ALSA: hda - Add AZX_DCAPS_SNOOP_OFF (and refactor snoop setup) (boo#934755). - ALSA: hda - Add Conexant codecs CX20721, CX20722, CX20723 and CX20724 (boo#934755). - ALSA: hda - Add common pin macros for ALC269 family (boo#934755). - ALSA: hda - Add dock support for ThinkPad X250 (17aa:2226) (boo#934755). - ALSA: hda - Add dock support for Thinkpad T450s (17aa:5036) (boo#934755). - ALSA: hda - Add headphone quirk for Lifebook E752 (boo#934755). - ALSA: hda - Add headset mic quirk for Dell Inspiron 5548 (boo#934755). - ALSA: hda - Add mute-LED mode control to Thinkpad (boo#934755). - ALSA: hda - Add one more node in the EAPD supporting candidate list (boo#934755). - ALSA: hda - Add pin configs for ASUS mobo with IDT 92HD73XX codec (boo#934755). - ALSA: hda - Add ultra dock support for Thinkpad X240 (boo#934755). - ALSA: hda - Add workaround for CMI8888 snoop behavior (boo#934755). - ALSA: hda - Add workaround for MacBook Air 5,2 built-in mic (boo#934755). - ALSA: hda - Disable runtime PM for Panther Point again (boo#934755). - ALSA: hda - Do not access stereo amps for mono channel widgets (boo#934755). - ALSA: hda - Fix Dock Headphone on Thinkpad X250 seen as a Line Out (boo#934755). - ALSA: hda - Fix headphone pin config for Lifebook T731 (boo#934755). - ALSA: hda - Fix noise on AMD radeon 290x controller (boo#934755). - ALSA: hda - Fix probing and stuttering on CMI8888 HD-audio controller (boo#934755). - ALSA: hda - One more Dell macine needs DELL1_MIC_NO_PRESENCE quirk (boo#934755). - ALSA: hda - One more HP machine needs to change mute led quirk (boo#934755). - ALSA: hda - Set GPIO 4 low for a few HP machines (boo#934755). - ALSA: hda - Set single_adc_amp flag for CS420x codecs (boo#934755). - ALSA: hda - Treat stereo-to-mono mix properly (boo#934755). - ALSA: hda - change three SSID quirks to one pin quirk (boo#934755). - ALSA: hda - fix last seen 2020-06-05 modified 2015-08-17 plugin id 85432 published 2015-08-17 reporter This script is Copyright (C) 2015-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/85432 title openSUSE Security Update : the Linux Kernel (openSUSE-2015-543)
