An update that fixes four vulnerabilities is now available.

Description:

This update for teeworlds fixes the following issues:

– CVE-2019-10879: An integer overflow in CDataFileReader::Open() could
have lead to a buffer overflow and possibly remote code execution,
because size-related multiplications were mishandled. (boo#1131729)
– CVE-2019-10878: A failed bounds check in CDataFileReader::GetData() and
CDataFileReader::ReplaceData() and related functions could have lead to
an arbitrary free and out-of-bounds pointer write, possibly resulting in
remote code execution.
– CVE-2019-10877: An integer overflow in CMap::Load() could have lead to a
buffer overflow, because multiplication of width and height were
mishandled.
– CVE-2018-18541: Connection packets could have been forged. There was no
challenge-response involved in the connection build up. A remote
attacker could have sent connection packets from a spoofed IP address
and occupy all server slots, or even use them for a reflection attack
using map download packets. (boo#1112910)
