FreeBSD : Teeworlds -- Buffer Overflow (5aaf534c-a069-11ec-acdc-14dae9d5a9d2)

high Nessus Plugin ID 158787

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 5aaf534c-a069-11ec-acdc-14dae9d5a9d2 advisory.

 - Teeworlds up to and including 0.7.5 is vulnerable to Buffer Overflow. A map parser does not validate m_Channels value coming from a map file, leading to a buffer overflow. A malicious server may offer a specially crafted map that will overwrite client's stack causing denial of service or code execution.
 (CVE-2021-43518)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
