medium Nessus Plugin ID 165286

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5621-1 advisory.

 - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds. (CVE-2021-33655)

 - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)

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.
