概要

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

説明

Gleb Napatov discovered that KVM did not correctly check certain privileged operations. A local attacker with access to a guest kernel could exploit this to crash the host system, leading to a denial of service. (CVE-2010-0435)

Dan Jacobson discovered that ThinkPad video output was not correctly access controlled. A local attacker could exploit this to hang the system, leading to a denial of service. (CVE-2010-3448)

It was discovered that KVM did not correctly initialize certain CPU registers. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-3698)

Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. (CVE-2010-3859)

Thomas Pollet discovered that the RDS network protocol did not check certain iovec buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user.
(CVE-2010-3865)

Dan Rosenberg discovered that the Linux kernel X.25 implementation incorrectly parsed facilities. A remote attacker could exploit this to crash the kernel, leading to a denial of service. (CVE-2010-3873)

Dan Rosenberg discovered that the CAN protocol on 64bit systems did not correctly calculate the size of certain buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. (CVE-2010-3874)

Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-3875)

Vasiliy Kulikov discovered that the Linux kernel sockets implementation did not properly initialize certain structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-3876)

Vasiliy Kulikov discovered that the TIPC interface did not correctly initialize certain structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-3877)

Nelson Elhage discovered that the Linux kernel IPv4 implementation did not properly audit certain bytecodes in netlink messages. A local attacker could exploit this to cause the kernel to hang, leading to a denial of service. (CVE-2010-3880)

Dan Rosenberg discovered that IPC structures were not correctly initialized on 64bit systems. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-4073)

Dan Rosenberg discovered that the USB subsystem did not correctly initialize certian structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-4074)

Dan Rosenberg discovered that the SiS video driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4078)

Dan Rosenberg discovered that the ivtv V4L driver did not correctly initialize certian structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-4079)

Dan Rosenberg discovered that the RME Hammerfall DSP audio interface driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4080, CVE-2010-4081)

Dan Rosenberg discovered that the VIA video driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4082)

Dan Rosenberg discovered that the semctl syscall did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4083)

James Bottomley discovered that the ICP vortex storage array controller driver did not validate certain sizes. A local attacker on a 64bit system could exploit this to crash the kernel, leading to a denial of service. (CVE-2010-4157)

Dan Rosenberg discovered that the Linux kernel L2TP implementation contained multiple integer signedness errors. A local attacker could exploit this to to crash the kernel, or possibly gain root privileges.
(CVE-2010-4160)

Steve Chen discovered that setsockopt did not correctly check MSS values. A local attacker could make a specially crafted socket call to crash the system, leading to a denial of service. (CVE-2010-4165)

Dave Jones discovered that the mprotect system call did not correctly handle merged VMAs. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-4169)

It was discovered that multithreaded exec did not handle CPU timers correctly. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-4248)

Vegard Nossum discovered that memory garbage collection was not handled correctly for active sockets. A local attacker could exploit this to allocate all available kernel memory, leading to a denial of service. (CVE-2010-4249).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
