Ubuntu 10.04 LTS : linux vulnerabilities (USN-2441-1)

high Nessus Plugin ID 80028

Language:

Synopsis

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

Description

An information leak in the Linux kernel was discovered that could leak the high 16 bits of the kernel stack address on 32-bit Kernel Virtual Machine (KVM) paravirt guests. A user in the guest OS could exploit this leak to obtain information that could potentially be used to aid in attacking the kernel. (CVE-2014-8134)

A flaw in the handling of malformed ASCONF chunks by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel was discovered. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2014-3673)

A flaw in the handling of duplicate ASCONF chunks by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel was discovered. A remote attacker could exploit this flaw to cause a denial of service (panic). (CVE-2014-3687)

It was discovered that excessive queuing by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel can cause memory pressure. A remote attacker could exploit this flaw to cause a denial of service. (CVE-2014-3688)

A NULL pointer dereference flaw was discovered in the the Linux kernel's SCTP implementation when ASCONF is used. A remote attacker could exploit this flaw to cause a denial of service (system crash) via a malformed INIT chunk. (CVE-2014-7841)

Jouni Malinen reported a flaw in the handling of fragmentation in the mac8Linux subsystem of the kernel. A remote attacker could exploit this flaw to obtain potential sensitive cleartext information by reading packets. (CVE-2014-8709)

A stack buffer overflow was discovered in the ioctl command handling for the Technotrend/Hauppauge USB DEC devices driver. A local user could exploit this flaw to cause a denial of service (system crash) or possibly gain privileges. (CVE-2014-8884)

Andy Lutomirski discovered that the Linux kernel does not properly handle faults associated with the Stack Segment (SS) register on the x86 architecture. A local attacker could exploit this flaw to cause a denial of service (panic). (CVE-2014-9090).

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.

Solution
