--===============0803794761084923509== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="tcC6YSqBgqqkz7Sb" Content-Disposition: inline --tcC6YSqBgqqkz7Sb Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-3017-3 June 27, 2016 linux-lts-wily vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux-lts-wily: Linux hardware enablement kernel from Wily for Trusty Details: USN-3017-1 fixed vulnerabilities in the Linux kernel for Ubuntu 15.10. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 15.10 for Ubuntu 14.04 LTS. Jesse Hertz and Tim Newsham discovered that the Linux netfilter implementation did not correctly perform validation when handling 32 bit compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local unprivileged attacker could use this to cause a denial of service (system crash) or execute arbitrary code with administrative privileges. (CVE-2016-4997) Kangjie Lu discovered an information leak in the core USB implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4482) Kangjie Lu discovered an information leak in the timer handling implementation in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4569, CVE-2016-4578) Kangjie Lu discovered an information leak in the X.25 Call Request handling in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4580) It was discovered that an information leak exists in the Rock Ridge implementation in the Linux kernel. A local attacker who is able to mount a malicious iso9660 file system image could exploit this flaw to obtain potentially sensitive information from kernel memory. (CVE-2016-4913) Baozeng Ding discovered that the Transparent Inter-process Communication (TIPC) implementation in the Linux kernel did not verify socket existence before use in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-4951) Jesse Hertz and Tim Newsham discovered that the Linux netfilter implementation did not correctly perform validation when handling IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to cause a denial of service (system crash) or obtain potentially sensitive information from kernel memory. (CVE-2016-4998) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-4.2.0-41-generic 4.2.0-41.48~14.04.1 linux-image-4.2.0-41-generic-lpae 4.2.0-41.48~14.04.1 linux-image-4.2.0-41-lowlatency 4.2.0-41.48~14.04.1 linux-image-4.2.0-41-powerpc-e500mc 4.2.0-41.48~14.04.1 linux-image-4.2.0-41-powerpc-smp 4.2.0-41.48~14.04.1 linux-image-4.2.0-41-powerpc64-emb 4.2.0-41.48~14.04.1 linux-image-4.2.0-41-powerpc64-smp 4.2.0-41.48~14.04.1 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.
