USN-4171-5
apport regression
USN-4171-1 fixed vulnerabilities in Apport. This caused a regression in autopkgtest and python2 compatibility. This update fixes the problem.
We apologize for the inconvenience.
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)
