Ubuntu 16.04 LTS / 18.04 LTS : Perl DBI module vulnerability (USN-4534-1)

medium Nessus Plugin ID 140752

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-4534-1 advisory.

 - An issue was discovered in the DBI module before 1.643 for Perl. The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference. (CVE-2019-20919)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libdbi-perl package.
