CVE-2019-15161

Published: 30 September 2019

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.

Notes

AuthorNote
sbeattie
this is likely actually fixed by
449d95265252b291711899fd288836414791930d, and thus only affects
windows platforms.
even if accurate, it's against the libpcap daemon, introduced
in 1.9.0 and is not included in debian/ubuntu packaging
