Description Pedro Sampaio 2019-10-10 23:38:55 UTC
rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF because a URL may be provided as a capture source.

Upstream patch:

https://github.com/the-tcpdump-group/libpcap/commit/33834cb2a4d035b52aa2a26742f832a112e90a0a

Comment 1 Pedro Sampaio 2019-10-10 23:58:10 UTC
Created libpcap tracking bugs for this issue:

Affects: fedora-all [bug 1760624]

Comment 2 Riccardo Schirone 2020-01-16 15:57:50 UTC
RPCAPD support added in tcpdump 1.9.0 (see https://github.com/the-tcpdump-group/libpcap/blob/libpcap-1.9/CHANGES#L74).

Comment 3 Riccardo Schirone 2020-01-16 16:03:39 UTC
RHEL 6 and 7 ship an older version of libpcap that does not even have the vulnerable file.
RHEL 8 ships a newer version, however it is not compiled with RPCAPD support (--enable-remote is not specified).

Comment 4 Riccardo Schirone 2020-01-16 16:03:44 UTC
Statement:

This issue did not affect the versions of libpcap as shipped with Red Hat Enterprise Linux 6, 7, and 8 as they did not include support for RPCAPD.

Comment 5 Product Security DevOps Team 2020-01-16 20:09:28 UTC
This bug is now closed. Further updates for individual products will be reflected on the CVE page(s):
