Ubuntu 16.04 LTS / 18.04 LTS : Linux kernel vulnerabilities (USN-4210-1)

critical Nessus Plugin ID 131564

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4210-1 advisory.

 - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)

 - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.
 This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)

 - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

 - A memory leak in the adis_update_scan_mode() function in drivers/iio/imu/adis_buffer.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-ab612b1daf41.
 (CVE-2019-19060)

 - A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering rhashtable_init() failures, aka CID-34b3be18a04e. NOTE: This has been disputed as not a vulnerability because rhashtable_init() can only fail if it is passed invalid values in the second parameter's struct, but when invoked from sdma_init() that is a pointer to a static const struct, so an attacker could only trigger failure if they could corrupt kernel memory (in which case a small memory leak is not a significant problem). (CVE-2019-19065)

 - A memory leak in the ca8210_probe() function in drivers/net/ieee802154/ca8210.c in the Linux kernel before 5.3.8 allows attackers to cause a denial of service (memory consumption) by triggering ca8210_get_platform_data() failures, aka CID-6402939ec86e. (CVE-2019-19075)

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.
