CVE-2020-15702

TOCTOU Race Condition vulnerability in apport allows a local attacker to escalate privileges and execute arbitrary code. An attacker may exit the crashed process and exploit PID recycling to spawn a root process with the same PID as the crashed process, which can then be used to escalate privileges. Fixed in 2.20.1-0ubuntu2.24, 2.20.9 versions prior to 2.20.9-0ubuntu7.16 and 2.20.11 versions prior to 2.20.11-0ubuntu27.6. Was ZDI-CAN-11234.

Ryota Shiga working with Trend Micro´s Zero Day Initiative, discovered that Apport incorrectly dropped privileges when making certain D-Bus calls. A local attacker could use this issue to read arbitrary files. (CVE-2020-11936)

Seong-Joong Kim discovered that Apport incorrectly parsed configuration files. A local attacker could use this issue to cause Apport to crash, resulting in a denial of service. (CVE-2020-15701)

Ryota Shiga working with Trend Micro´s Zero Day Initiative, discovered that Apport incorrectly implemented certain checks. A local attacker could use this issue to escalate privileges and run arbitrary code. (CVE-2020-15702)

USN-4449-1 fixed several vulnerabilities in Apport. This update provides the corresponding update for Ubuntu 14.04 ESM.
