apport vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in Apport.
Software Description
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)
