Summary

apport regression

Details

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)
