Ubuntu 14.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS : Perl vulnerability (USN-9006-1)

high Nessus Plugin ID 380038

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-9006-1 advisory.

 It was discovered that Pod::Text in Perl did not properly handle POD documents with deeply nested =over directives. If a user or automated system were tricked into processing a specially crafted file, an attacker could possibly use this issue to cause CPU and memory exhaustion, resulting in a denial of service.

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

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 packages.
