Ubuntu 16.04 LTS : GNU C Library vulnerabilities (USN-4954-1)

high Nessus Plugin ID 149477

Synopsis

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

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4954-1 advisory.

Jason Royes and Samuel Dytrych discovered that the memcpy() implementation for 32 bit ARM processors in the GNU C Library contained an integer underflow vulnerability. An attacker could possibly use this to cause a denial of service (application crash) or execute arbitrary code. (CVE-2020-6096)

It was discovered that the POSIX regex implementation in the GNU C Library did not properly parse alternatives. An attacker could use this to cause a denial of service. (CVE-2009-5155)

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.
