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 local users. This can happen through either a crafted BMP file with RLE compression or by using crafted dimensions in a BMP file. The potential impact includes causing a denial of service, which could result in a daemon crash, or possibly gaining privileges.

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 use of BMP files with RLE compression or limiting the dimensions of BMP files to minimize the risk of exploitation.
