Alpine: multiple wireshark packages, tshark: security update to 2.6.2-r0

high Tenable Cloud Security Plugin ID 427529

Description

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

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the Bazaar protocol dissector could go
into an infinite loop. This was addressed in epan/dissectors/packet-bzr.c by properly handling items that
are too long. (CVE-2018-14368)

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the MMSE dissector could go into an
infinite loop. This was addressed in epan/proto.c by adding offset and length validation. (CVE-2018-14339)

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, dissectors that support zlib
decompression could crash. This was addressed in epan/tvbuff_zlib.c by rejecting negative lengths to avoid
a buffer over-read. (CVE-2018-14340)

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the DICOM dissector could go into a
large or infinite loop. This was addressed in epan/dissectors/packet-dcm.c by preventing an offset
overflow. (CVE-2018-14341)

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the BGP protocol dissector could go into
a large loop. This was addressed in epan/dissectors/packet-bgp.c by validating Path Attribute lengths.
(CVE-2018-14342)
