9 December 2024

tinyproxy could be made to expose sensitive information.

Releases
Ubuntu 22.04 LTS Ubuntu 20.04 LTS Ubuntu 18.04 ESM Ubuntu 16.04 ESM

Packages
tinyproxy - Lightweight, non-caching, optionally anonymizing HTTP proxy

Details
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.

Update instructions
The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04

• tinyproxy - 1.11.0-1ubuntu0.1~esm1
• tinyproxy-bin - 1.11.0-1ubuntu0.1~esm1

Ubuntu 16.04
