high Nessus Plugin ID 56257

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Goldwyn Rodrigues discovered that the OCFS2 filesystem did not correctly clear memory when writing certain file holes. A local attacker could exploit this to read uninitialized data from the disk, leading to a loss of privacy. (CVE-2011-0463)

Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. (CVE-2011-1017)

It was discovered that the /proc filesystem did not correctly handle permission changes when programs executed. A local attacker could hold open files to examine details about programs running with higher privileges, potentially increasing the chances of exploiting additional vulnerabilities. (CVE-2011-1020)

Vasiliy Kulikov discovered that the Bluetooth stack did not correctly clear memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2011-1078)

Vasiliy Kulikov discovered that the Bluetooth stack did not correctly check that device name strings were NULL terminated. A local attacker could exploit this to crash the system, leading to a denial of service, or leak contents of kernel stack memory, leading to a loss of privacy. (CVE-2011-1079)

Vasiliy Kulikov discovered that bridge network filtering did not check that name fields were NULL terminated. A local attacker could exploit this to leak contents of kernel stack memory, leading to a loss of privacy. (CVE-2011-1080)

Peter Huewe discovered that the TPM device did not correctly initialize memory. A local attacker could exploit this to read kernel heap memory contents, leading to a loss of privacy. (CVE-2011-1160)

Vasiliy Kulikov discovered that the netfilter code did not check certain strings copied from userspace. A local attacker with netfilter access could exploit this to read kernel memory or crash the system, leading to a denial of service. (CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, CVE-2011-2534)

Vasiliy Kulikov discovered that the Acorn Universal Networking driver did not correctly initialize memory. A remote attacker could send specially crafted traffic to read kernel stack memory, leading to a loss of privacy. (CVE-2011-1173)

Dan Rosenberg discovered that the IRDA subsystem did not correctly check certain field sizes. If a system was using IRDA, a remote attacker could send specially crafted traffic to crash the system or gain root privileges. (CVE-2011-1180)

Julien Tinnes discovered that the kernel did not correctly validate the signal structure from tkill(). A local attacker could exploit this to send signals to arbitrary threads, possibly bypassing expected restrictions. (CVE-2011-1182)

Dan Rosenberg discovered that the X.25 Rose network stack did not correctly handle certain fields. If a system was running with Rose enabled, a remote attacker could send specially crafted traffic to gain root privileges. (CVE-2011-1493)

Dan Rosenberg discovered that MPT devices did not correctly validate certain values in ioctl calls. If these drivers were loaded, a local attacker could exploit this to read arbitrary kernel memory, leading to a loss of privacy. (CVE-2011-1494, CVE-2011-1495)

Timo Warns discovered that the GUID partition parsing routines did not correctly validate certain structures. A local attacker with physical access could plug in a specially crafted block device to crash the system, leading to a denial of service. (CVE-2011-1577)

Phil Oester discovered that the network bonding system did not correctly handle large queues. On some systems, a remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. (CVE-2011-1581)

Tavis Ormandy discovered that the pidmap function did not correctly handle large requests. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-1593)

Oliver Hartkopp and Dave Jones discovered that the CAN network driver did not correctly validate certain socket structures. If this driver was loaded, a local attacker could crash the system, leading to a denial of service. (CVE-2011-1598, CVE-2011-1748)

Vasiliy Kulikov discovered that the AGP driver did not check certain ioctl values. A local attacker with access to the video subsystem could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges. (CVE-2011-1745, CVE-2011-2022)

Vasiliy Kulikov discovered that the AGP driver did not check the size of certain memory allocations. A local attacker with access to the video subsystem could exploit this to run the system out of memory, leading to a denial of service. (CVE-2011-1746)

Dan Rosenberg discovered that the DCCP stack did not correctly handle certain packet structures. A remote attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-1770)

Ben Greear discovered that CIFS did not correctly handle direct I/O.
A local attacker with access to a CIFS partition could exploit this to crash the system, leading to a denial of service. (CVE-2011-1771)

Vasiliy Kulikov and Dan Rosenberg discovered that ecryptfs did not correctly check the origin of mount points. A local attacker could exploit this to trick the system into unmounting arbitrary mount points, leading to a denial of service. (CVE-2011-1833)

Vasiliy Kulikov discovered that taskstats listeners were not correctly handled. A local attacker could expoit this to exhaust memory and CPU resources, leading to a denial of service.
(CVE-2011-2484)

It was discovered that Bluetooth l2cap and rfcomm did not correctly initialize structures. A local attacker could exploit this to read portions of the kernel stack, leading to a loss of privacy.
(CVE-2011-2492)

Sami Liedes discovered that ext4 did not correctly handle missing root inodes. A local attacker could trigger the mount of a specially crafted filesystem to cause the system to crash, leading to a denial of service. (CVE-2011-2493)

It was discovered that GFS2 did not correctly check block sizes. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-2689)

Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service.
(CVE-2011-2699)

The performance counter subsystem did not correctly handle certain counters. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-2918)
