CWE-131  (opens in a new tab)

How to fix?

Upgrade Debian:13 libpcap to version 1.9.1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libpcap package and not the libpcap package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

rpcapd/daemon.c in libpcap before 1.9.1 mishandles certain length values because of reuse of a variable. This may open up an attack vector involving extra data at the end of a request.
