Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-7140-1 advisory.

 It was discovered that Tinyproxy did not properly manage memory under certain circumstances. An attacker could possibly use this issue to leak left-over heap data if custom error page templates containing special non-standard variables are used.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
