CVSS v2.0

7.5

High

Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions OpenTTD versions prior to 1.1.3

Description The issue is related to multiple buffer overflows that can be triggered by loading specific chunks from a savegame, including NAME, PLYR, CHTS, or AIPL (also known as AI config). This can cause a denial of service, resulting in a daemon crash, or potentially allow the execution of arbitrary code.

Recommendations For versions prior to 1.1.3, update to version 1.1.3 or later to resolve the issue. As a temporary workaround, consider restricting the loading of savegames from untrusted sources to minimize the risk of exploitation.
