USN-4171-1: Apport vulnerabilities
30 October 2019
apport vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 19.10
o Ubuntu 19.04
o Ubuntu 18.04 LTS
o Ubuntu 16.04 LTS
Summary
Several security issues were fixed in Apport.
Software Description
o apport - automatically generate crash reports for debugging
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)
