Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3343-1)

high Nessus Plugin ID 101152

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-3343-1 advisory.

 - The regulator_ena_gpio_free function in drivers/regulator/core.c in the Linux kernel before 3.19 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted application.
 (CVE-2014-9940)

 - Linux drivers/char/lp.c Out-of-Bounds Write. Due to a missing bounds check, and the fact that parport_ptr integer is static, a 'secure boot' kernel command line adversary (can happen due to bootloader vulns, e.g.
 Google Nexus 6's CVE-2016-10277, where due to a vulnerability the adversary has partial control over the command line) can overflow the parport_nr array in the following code, by appending many (>LP_NO) 'lp=none' arguments to the command line. (CVE-2017-1000363)

 - The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.6 does not validate addition of certain levels data, which allows local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device. (CVE-2017-7294)

 - The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel through 4.10.15 allows attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call. (CVE-2017-8890)

 - The IPv6 fragmentation implementation in the Linux kernel through 4.11.1 does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. (CVE-2017-9074)

 - The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel through 4.11.1 mishandles inheritance, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890. (CVE-2017-9075)

 - The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel through 4.11.1 mishandles inheritance, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890. (CVE-2017-9076)

 - The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel through 4.11.1 mishandles inheritance, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890. (CVE-2017-9077)

 - The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel through 4.11.3 is too late in checking whether an overwrite of an skb data structure may occur, which allows local users to cause a denial of service (system crash) via crafted system calls. (CVE-2017-9242)

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.
