Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-2663-1)

medium Nessus Plugin ID 84614

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2663-1 advisory.

 - The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.
 (CVE-2014-9710)

 - Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function.
 (CVE-2015-1420)

 - Integer signedness error in the oz_hcd_get_desc_cnf function in drivers/staging/ozwpan/ozhcd.c in the OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted packet. (CVE-2015-4001)

 - drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 does not ensure that certain length values are sufficiently large, which allows remote attackers to cause a denial of service (system crash or large loop) or possibly execute arbitrary code via a crafted packet, related to the (1) oz_usb_rx and (2) oz_usb_handle_ep_data functions. (CVE-2015-4002)

 - The oz_usb_handle_ep_data function in drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service (divide-by-zero error and system crash) via a crafted packet. (CVE-2015-4003)

 - The udf_read_inode function in fs/udf/inode.c in the Linux kernel before 3.19.1 does not validate certain length values, which allows local users to cause a denial of service (incorrect data representation or integer overflow, and OOPS) via a crafted UDF filesystem. (CVE-2015-4167)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
