TITLE:
Gentoo warzone2100 Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA21474

VERIFY ADVISORY:
http://secunia.com/advisories/21474/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

OPERATING SYSTEM:
Gentoo Linux 1.x
http://secunia.com/product/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.
