========================================================================== Ubuntu Security Notice USN-3617-3 April 04, 2018
linux-raspi2 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-raspi2: Linux kernel for Raspberry Pi 2
Details:
It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-0861)
It was discovered that a use-after-free vulnerability existed in the network namespaces implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15129)
Andrey Konovalov discovered that the usbtest device driver in the Linux kernel did not properly validate endpoint metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16532)
Andrey Konovalov discovered that the SoundGraph iMON USB driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16537)
Andrey Konovalov discovered that the IMS Passenger Control Unit USB driver in the Linux kernel did not properly validate device descriptors. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16645)
Andrey Konovalov discovered that the DiBcom DiB0700 USB DVB driver in the Linux kernel did not properly handle detach events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16646)
Andrey Konovalov discovered that the ASIX Ethernet USB driver in the Linux kernel did not properly handle suspend and resume events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16647)
Andrey Konovalov discovered that the CDC USB Ethernet driver did not properly validate device descriptors. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16649)
Andrey Konovalov discovered that the QMI WWAN USB driver did not properly validate device descriptors. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16650)
It was discovered that the HugeTLB component of the Linux kernel did not properly handle holes in hugetlb ranges. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-16994)
It was discovered that the netfilter component of the Linux did not properly restrict access to the connection tracking helpers list. A local attacker could use this to bypass intended access restrictions. (CVE-2017-17448)
It was discovered that the netfilter passive OS fingerprinting (xt_osf) module did not properly perform access control checks. A local attacker could improperly modify the system-wide OS fingerprint list. (CVE-2017-17450)
Dmitry Vyukov discovered that the KVM implementation in the Linux kernel contained an out-of-bounds read when handling memory-mapped I/O. A local attacker could use this to expose sensitive information. (CVE-2017-17741)
It was discovered that the Salsa20 encryption algorithm implementations in the Linux kernel did not properly handle zero-length inputs. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-17805)
It was discovered that the HMAC implementation did not validate the state of the underlying cryptographic hash algorithm. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-17806)
It was discovered that the keyring implementation in the Linux kernel did not properly check permissions when a key request was performed on a tasks' default keyring. A local attacker could use this to add keys to unauthorized keyrings. (CVE-2017-17807)
It was discovered that a race condition existed in the OCFS2 file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2017-18204)
It was discovered that the Broadcom NetXtremeII ethernet driver in the Linux kernel did not properly validate Generic Segment Offload (GSO) packet sizes. An attacker could use this to cause a denial of service (interface unavailability). (CVE-2018-1000026)
It was discovered that the Reliable Datagram Socket (RDS) implementation in the Linux kernel contained an out-of-bounds during RDMA page allocation. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-5332)
Mohamed Ghannam discovered a null pointer dereference in the RDS (Reliable Datagram Sockets) protocol implementation of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-5333)
èéŸé£ discovered that a race condition existed in loop block device implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-5344)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.10: linux-image-4.13.0-1016-raspi2 4.13.0-1016.17 linux-image-raspi2 4.13.0.1016.14
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
