============================================================================ Ubuntu Security Notice USN-1837-1 May 24, 2013 linux vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 13.04 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: An information leak was discovered in the Linux kernel's crypto API. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3076) An information leak was discovered in the Linux kernel's rcvmsg path for ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3222) An information leak was discovered in the Linux kernel's recvmsg path for ax25 address family. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3223) An information leak was discovered in the Linux kernel's recvmsg path for the bluetooth address family. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3224) An information leak was discovered in the Linux kernel's bluetooth rfcomm protocol support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3225) An information leak was discovered in the Linux kernel's bluetooth SCO sockets implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3226) An information leak was discovered in the Linux kernel's CAIF protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3227) An information leak was discovered in the Linux kernel's IRDA (infrared) support subsystem. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3228) An information leak was discovered in the Linux kernel's s390 - z/VM support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3229) An information leak was discovered in the Linux kernel's l2tp (Layer Two Tunneling Protocol) implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3230) An information leak was discovered in the Linux kernel's llc (Logical Link Layer 2) support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3231) An information leak was discovered in the Linux kernel's nfc (near field communication) support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3233) An information leak was discovered in the Linux kernel's Rose X.25 protocol layer. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3234) An information leak was discovered in the Linux kernel's TIPC (Transparent Inter Process Communication) protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3235) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 13.04: linux-image-3.8.0-22-generic 3.8.0-22.33 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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
