CVE-2012-3421  (opens in a new tab)

How to fix?

Upgrade Debian:12 pcp to version 3.6.5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pcp package and not the pcp package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

The pduread function in pdu.c in libpcp in Performance Co-Pilot (PCP) before 3.6.5 does not properly time out connections, which allows remote attackers to cause a denial of service (pmcd hang) by sending individual bytes of a PDU separately, related to an "event-driven programming flaw."
