--===============2196741499435608447== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="rWhLK7VZz0iBluhq" Content-Disposition: inline --rWhLK7VZz0iBluhq Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-3017-1 June 27, 2016 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 15.10 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: 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 15.10: linux-image-4.2.0-41-generic 4.2.0-41.48 linux-image-4.2.0-41-generic-lpae 4.2.0-41.48 linux-image-4.2.0-41-lowlatency 4.2.0-41.48 linux-image-4.2.0-41-powerpc-e500mc 4.2.0-41.48 linux-image-4.2.0-41-powerpc-smp 4.2.0-41.48 linux-image-4.2.0-41-powerpc64-emb 4.2.0-41.48 linux-image-4.2.0-41-powerpc64-smp 4.2.0-41.48 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.
