USN-4117-1: Linux kernel (AWS) vulnerabilities<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
It was discovered that a heap buffer overflow existed in the Marvell
\nWireless LAN device driver for the Linux kernel. An attacker could use this
\nto cause a denial of service (system crash) or possibly execute arbitrary
\ncode. (CVE-2019-10126)<\/p>\n
Amit Klein and Benny Pinkas discovered that the Linux kernel did not
\nsufficiently randomize IP ID values generated for connectionless networking
\nprotocols. A remote attacker could use this to track particular Linux
\ndevices. (CVE-2019-10638)<\/p>\n
It was discovered that a NULL pointer dereference vulnerability existed in
\nthe Near-field communication (NFC) implementation in the Linux kernel. A
\nlocal attacker could use this to cause a denial of service (system crash).
\n(CVE-2019-12984)<\/p>\n
Jann Horn discovered a use-after-free vulnerability in the Linux kernel
\nwhen accessing LDT entries in some situations. A local attacker could use
\nthis to cause a denial of service (system crash) or possibly execute
\narbitrary code. (CVE-2019-13233)<\/p>\n
Jann Horn discovered that the ptrace implementation in the Linux kernel did
\nnot properly record credentials in some situations. A local attacker could
\nuse this to cause a denial of service (system crash) or possibly gain
\nadministrative privileges. (CVE-2019-13272)<\/p>\n
It was discovered that the floppy driver in the Linux kernel did not
\nproperly validate meta data, leading to a buffer overread. A local attacker
\ncould use this to cause a denial of service (system crash).
\n(CVE-2019-14283)<\/p>\n
It was discovered that the floppy driver in the Linux kernel did not
\nproperly validate ioctl() calls, leading to a division-by-zero. A local
\nattacker could use this to cause a denial of service (system crash).
\n(CVE-2019-14284)<\/p>\n
It was discovered that the Marvell Wireless LAN device driver in the Linux
\nkernel did not properly validate the BSS descriptor. A local attacker could
\npossibly use this to cause a denial of service (system crash) or possibly
\nexecute arbitrary code. (CVE-2019-3846)<\/p>\n
Jason Wang discovered that an infinite loop vulnerability existed in the
\nvirtio net driver in the Linux kernel. A local attacker in a guest VM could
\npossibly use this to cause a denial of service in the host system.
\n(CVE-2019-3900)<\/p>\n
The problem can be corrected by updating your system to the following package versions:<\/p>\n
To update your system, please follow these instructions: https:\/\/wiki.ubuntu.com\/Security\/Upgrades<\/a>.<\/p>\n After a standard system update you need to reboot your computer to make ATTENTION: Due to an unavoidable ABI change the kernel updates have Source: USN-4117-1: Linux kernel (AWS) vulnerabilities<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" USN-4117-1: Linux kernel (AWS) vulnerabilities linux-aws vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 19.04 Summary Several security issues were fixed in the Linux kernel.

\nall the necessary changes.<\/p>\n
\nbeen given a new version number, which requires you to recompile and
\nreinstall all third party kernel modules you might have installed.
\nUnless you manually uninstalled the standard kernel metapackages
\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
\nlinux-powerpc), a standard system upgrade will automatically perform
\nthis as well.<\/p>\nReferences<\/h2>\n
