New ppp packages are available for Slackware 14.0, 14.1, 14.2, and -current to
fix a security issue.

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/ppp-2.4.8-i586-1_slack14.2.txz: Upgraded.
This update fixes a security issue:
By sending an unsolicited EAP packet to a vulnerable ppp client or server,
an unauthenticated remote attacker could cause memory corruption in the
pppd process, which may allow for arbitrary code execution.
For more information, see:
https://vulners.com/cve/CVE-2020-8597
(* Security fix *)

Where to find the new packages:
