DSA-2668-1 linux-2.6 -- privilege escalation/denial of service/information leak

ID: oval:org.secpod.oval:def:601014Date: (C)2013-05-15   (M)2024-02-19
Class: PATCHFamily: unix




Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2012-2121 Benjamin Herrenschmidt and Jason Baron discovered issues with the IOMMU mapping of memory slots used in KVM device assignment. Local users with the ability to assign devices could cause a denial of service due to a memory page leak. CVE-2012-3552 Hafid Lin reported an issue in the IP networking subsystem. A remote user can cause a denial of service on servers running applications that set options on sockets which are actively being processed. CVE-2012-4461 Jon Howell reported a denial of service issue in the KVM subsystem. On systems that do not support the XSAVE feature, local users with access to the /dev/kvm interface can cause a system crash. CVE-2012-4508 Dmitry Monakhov and Theodore Ts"o reported a race condition in the ext4 filesystem. Local users could gain access to sensitive kernel memory. CVE-2012-6537 Mathias Krause discovered information leak issues in the Transformation user configuration interface. Local users with the CAP_NET_ADMIN capability can gain access to sensitive kernel memory. CVE-2012-6539 Mathias Krause discovered an issue in the networking subsystem. Local users on 64-bit systems can gain access to sensitive kernel memory. CVE-2012-6540 Mathias Krause discovered an issue in the Linux virtual server subsystem. Local users can gain access to sensitive kernel memory. Note: this issue does not affect Debian provided kernels, but may affect custom kernels built from Debian"s linux-source-2.6.32 package. CVE-2012-6542 Mathias Krause discovered an issue in the LLC protocol support code. Local users can gain access to sensitive kernel memory. CVE-2012-6544 Mathias Krause discovered issues in the Bluetooth subsystem. Local users can gain access to sensitive kernel memory. CVE-2012-6545 Mathias Krause discovered issues in the Bluetooth RFCOMM protocol support. Local users can gain access to sensitive kernel memory. CVE-2012-6546 Mathias Krause discovered issues in the ATM networking support. Local users can gain access to sensitive kernel memory. CVE-2012-6548 Mathias Krause discovered an issue in the UDF file system support. Local users can obtain access to sensitive kernel memory. CVE-2012-6549 Mathias Krause discovered an issue in the isofs file system support. Local users can obtain access to sensitive kernel memory. CVE-2013-0349 Anderson Lizardo discovered an issue in the Bluetooth Human Interface Device Protocol stack. Local users can obtain access to sensitive kernel memory. CVE-2013-0914 Emese Revfy discovered an issue in the signal implementation. Local users maybe able to bypass the address space layout randomization facility due to a leaking of information to child processes. CVE-2013-1767 Greg Thelen reported an issue in the tmpfs virtual memory filesystem. Local users with sufficient privilege to mount filesystems can cause a denial of service or possibly elevated privileges due to a use-after- free defect. CVE-2013-1773 Alan Stern provided a fix for a defect in the UTF8->UTF16 string conversion facility used by the VFAT filesystem. A local user could cause a buffer overflow condition, resulting in a denial of service or potentially elevated privileges. CVE-2013-1774 Wolfgang Frisch provided a fix for a NULL-pointer dereference defect in the driver for some serial USB devices from Inside Out Networks. Local users with permission to access these devices can create a denial of service by causing the device to be removed while it is in use. CVE-2013-1792 Mateusz Guzik of Red Hat EMEA GSS SEG Team discovered a race condition in the access key retention support in the kernel. A local user could cause a denial of service . CVE-2013-1796 Andrew Honig of Google reported an issue in the KVM subsystem. A user in a guest operating system could corrupt kernel memory, resulting in a denial of service. CVE-2013-1798 Andrew Honig of Google reported an issue in the KVM subsystem. A user in a guest operating system could cause a denial of service due to a use- after-free defect. CVE-2013-1826 Mathias Krause discovered an issue in the Transformation user configuration interface of the networking stack. A user with the CAP_NET_ADMIN capability maybe able to gain elevated privileges. CVE-2013-1860 Oliver Neukum discovered an issue in the USB CDC WCM Device Management driver. Local users with the ability to attach devices can cause a denial of service or potentially gain elevated privileges. CVE-2013-1928 Kees Cook provided a fix for an information leak in the VIDEO_SET_SPU_PALETTE ioctl for 32-bit applications running on a 64-bit kernel. Local users can gain access to sensitive kernel memory. CVE-2013-1929 Oded Horovitz and Brad Spengler reported an issue in the device driver for Broadcom Tigon3 based gigabit Ethernet. Users with the ability to attach untrusted devices can create an overflow condition, resulting in a denial of service or elevated privileges. CVE-2013-2015 Theodore Ts"o provided a fix for an issue in the ext4 filesystem. Local users with the ability to mount a specially crafted filesystem can cause a denial of service . CVE-2013-2634 Mathias Krause discovered a few issues in the Data Center Bridging netlink interface. Local users can gain access to sensitive kernel memory. CVE-2013-3222 Mathias Krauss discovered an issue in the Asynchronous Transfer Mode protocol support. Local users can gain access to sensitive kernel memory. CVE-2013-3223 Mathias Krauss discovered an issue in the Amateur Radio AX.25 protocol support. Local users can gain access to sensitive kernel memory. CVE-2013-3224 Mathias Krauss discovered an issue in the Bluetooth subsystem. Local users can gain access to sensitive kernel memory. CVE-2013-3225 Mathias Krauss discovered an issue in the Bluetooth RFCOMM protocol support. Local users can gain access to sensitive kernel memory. CVE-2013-3228 Mathias Krauss discovered an issue in the IrDA subsystem support. Local users can gain access to sensitive kernel memory. CVE-2013-3229 Mathias Krauss discovered an issue in the IUCV support on s390 systems. Local users can gain access to sensitive kernel memory. CVE-2013-3231 Mathias Krauss discovered an issue in the ANSI/IEEE 802.2 LLC type 2 protocol support. Local users can gain access to sensitive kernel memory. CVE-2013-3234 Mathias Krauss discovered an issue in the Amateur Radio X.25 PLP protocol support. Local users can gain access to sensitive kernel memory. CVE-2013-3235 Mathias Krauss discovered an issue in the Transparent Inter Process Communication protocol support. Local users can gain access to sensitive kernel memory.
