TITLE:
Gentoo warzone2100 Buffer Overflow Vulnerabilities
SECUNIA ADVISORY ID:
SA21474
VERIFY ADVISORY:
http://secunia.c
om/advisories/21474/
CRITICAL:
Highly critical
IMPACT:
DoS, System access
WHERE:
From remote
OPERATING SYSTEM:
Gentoo Linux 1.x
http://secunia.com/pr
oduct/339/
DESCRIPTION:
Gentoo has acknowledged some vulnerabilities in warzone2100,
which
can be exploited by malicious people to cause a DoS (Denial
of
Service) and potentially compromise a vulnerable system.
1) A boundary error in the "recvTextMessage()"
function in
src/multiplay.c can be exploited to cause a buffer overflow
when
sending overly long text messages (larger than 256 bytes) to
a
server.
2) A boundary error in the "NETrecvFile()"
function in netplay.c can
be exploited to cause a buffer overflow by sending a overly
long
mapname (larger than 128 bytes) to the client.
Successful exploitation allows crashing a vulnerable server
or client
and potentially execution of arbitrary code.
SOLUTION:
Gentoo advises users to unmerge the
"games-strategy/warzone2100"
package.
