high Tenable Cloud Security Plugin ID 427022

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the RPC over RDMA dissector could go into an infinite
loop, triggered by packet injection or a malformed capture file. This was addressed in
epan/dissectors/packet-rpcrdma.c by correctly checking for going beyond the maximum offset.
(CVE-2017-7705)

- In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the NetScaler file parser could go into an infinite loop,
triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by ensuring a nonzero
record size. (CVE-2017-7700)

- In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the BGP dissector could go into an infinite loop,
triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-
bgp.c by using a different integer data type. (CVE-2017-7701)

- In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the WBXML dissector could go into an infinite loop,
triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-
wbxml.c by adding length validation. (CVE-2017-7702)

- In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the IMAP dissector could crash, triggered by packet
injection or a malformed capture file. This was addressed in epan/dissectors/packet-imap.c by calculating
a line's end correctly. (CVE-2017-7703)
