Debian DLA-2987-1 : libarchive - LTS security update

medium Nessus Plugin ID 160408

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2987 advisory.

- In Libarchive 3.4.0, archive_wstring_append_from_mbs in archive_string.c has an out-of-bounds read because of an incorrect mbrtowc or mbtowc call. For example, bsdtar crashes via a crafted archive.
(CVE-2019-19221)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the libarchive packages.

For Debian 9 stretch, these problems have been fixed in version 3.2.2-2+deb9u3.
