Ubuntu 16.04 ESM : GNU C Library vulnerabilities (USN-5310-2)

critical Nessus Plugin ID 158680

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5310-2 advisory.

 USN-5310-1 fixed several vulnerabilities in GNU. This update provides the corresponding update for Ubuntu 16.04 ESM.

 Original advisory details:

 It was discovered that the GNU C library getcwd function incorrectly

 handled buffers. An attacker could use this issue to cause the GNU C

 Library to crash, resulting in a denial of service, or possibly execute

 arbitrary code. (CVE-2021-3999)

 It was discovered that the GNU C Library sunrpc module incorrectly handled

 buffer lengths. An attacker could possibly use this issue to cause the GNU

 C Library to crash, resulting in a denial of service. (CVE-2022-23218,

 CVE-2022-23219)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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 packages.
