Debian DLA-3445-1 : cpio - LTS security update

high Nessus Plugin ID 176664

Language:

Synopsis

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

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3445 advisory.

- In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system. (CVE-2019-14866)

- GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data.
(CVE-2021-38185)

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 cpio packages.

For Debian 10 buster, these problems have been fixed in version 2.12+dfsg-9+deb10u1.
