Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : Apport regression (USN-4171-6)

info Nessus Plugin ID 142870

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4171-6 advisory.

 USN-4171-1 fixed vulnerabilities in Apport. The update caused a regression when handling configuration files. This update fixes the problem, and also introduces further hardening measures.

 Original advisory details:

 Kevin Backhouse discovered Apport would read its user-controlled settings

 file as the root user. This could be used by a local attacker to possibly

 crash Apport or have other unspecified consequences. (CVE-2019-11481)

 Sander Bos discovered a race-condition in Apport during core dump

 creation. This could be used by a local attacker to generate a crash report

 for a privileged process that is readable by an unprivileged user.

 (CVE-2019-11482)

 Sander Bos discovered Apport mishandled crash dumps originating from

 containers. This could be used by a local attacker to generate a crash

 report for a privileged process that is readable by an unprivileged user.

 (CVE-2019-11483)

 Sander Bos discovered Apport mishandled lock-file creation. This could be

 used by a local attacker to cause a denial of service against Apport.

 (CVE-2019-11485)

 Kevin Backhouse discovered Apport read various process-specific files with

 elevated privileges during crash dump generation. This could could be used

 by a local attacker to generate a crash report for a privileged process

 that is readable by an unprivileged user. (CVE-2019-15790)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
