CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected. CVE-2015-8767 An SCTP denial of service was discovered which can be triggered by a local attacker during a heartbeat timeout event after the 4-way handshake. CVE-2015-8785 It was discovered that local users permitted to write to a file on a FUSE filesystem could cause a denial of service (unkillable loop in the kernel). CVE-2016-0723 A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial of service. CVE-2016-2069 Andy Lutomirski discovered a race condition in flushing of the TLB when switching tasks. On an SMP system this could possibly lead to a crash, information leak or privilege escalation. For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze19. Additionally, this version includes upstream stable update 2.6.32.70. This is the final update to the linux-2.6 package for squeeze. For the oldstable distribution (wheezy), these problems will be fixed soon. For the stable distribution (jessie), CVE-2015-7566, CVE-2015-8767 and CVE-2016-0723 were fixed in linux version 3.16.7-ckt20-1+deb8u3 and the remaining problems will be fixed soon.

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 issue was previously mitigated for the stable suite by limiting the total number of files queued by each user on local sockets. The new kernel version in both suites includes that mitigation plus limits on the total size of pipe buffers allocated for each user. - CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected. - CVE-2015-8767 An SCTP denial-of-service was discovered which can be triggered by a local attacker during a heartbeat timeout event after the 4-way handshake. - CVE-2015-8785 It was discovered that local users permitted to write to a file on a FUSE filesystem could cause a denial of service (unkillable loop in the kernel). - CVE-2015-8812 A flaw was found in the iw_cxgb3 Infiniband driver. Whenever it could not send a packet because the network was congested, it would free the packet buffer but later attempt to send the packet again. This use-after-free could result in a denial of service (crash or hang), data loss or privilege escalation. - CVE-2015-8816 A use-after-free vulnerability was discovered in the USB hub driver. This may be used by a physically present user for privilege escalation. - CVE-2015-8830 Ben Hawkes of Google Project Zero reported that the AIO interface permitted reading or writing 2 GiB of data or more in a single chunk, which could lead to an integer overflow when applied to certain filesystems, socket or device types. The full security impact has not been evaluated. - CVE-2016-0723 A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial-of-service. - CVE-2016-0774 It was found that the fix for CVE-2015-1805 in kernel versions older than Linux 3.16 did not correctly handle the case of a partially failed atomic read. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space. - CVE-2016-2069 Andy Lutomirski discovered a race condition in flushing of the TLB when switching tasks on an x86 system. On an SMP system this could possibly lead to a crash, information leak or privilege escalation. - CVE-2016-2384 Andrey Konovalov found that a crafted USB MIDI device with an invalid USB descriptor could trigger a double-free. This may be used by a physically present user for privilege escalation. - CVE-2016-2543 Dmitry Vyukov found that the core sound sequencer driver (snd-seq) lacked a necessary check for a NULL pointer, allowing a user with access to a sound sequencer device to cause a denial-of service (crash). - CVE-2016-2544, CVE-2016-2546, CVE-2016-2547, CVE-2016-2548 Dmitry Vyukov found various race conditions in the sound subsystem (ALSA) last seen 2020-06-01 modified 2020-06-02 plugin id 89122 published 2016-03-04 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/89122 title Debian DSA-3503-1 : linux - security update NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-2909-1.NASL description halfdog discovered that OverlayFS, when mounting on top of a FUSE mount, incorrectly propagated file attributes, including setuid.
