TITLE:
MiMMS Media Stream Handling Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA20749

VERIFY ADVISORY:
http://secunia.com/advisories/20749/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
MiMMS 0.x
http://secunia.com/product/10605/

DESCRIPTION:
Anon Sricharoenchai has discovered some vulnerabilities in MiMMS,
which can be exploited by malicious people to cause a DoS (Denial of
Service) and potentially to compromise a user's system.

The vulnerabilities are caused due to boundary errors within the
"get_header()" and "get_media_packet" functions when read data from
the server. This can be exploited to cause stack-based buffer
overflows and may allow arbitrary code execution.

Successful exploitation requires that e.g. the user is tricked into
connecting to a malicious server.

The vulnerabilities have been confirmed in version 0.0.9. Other
versions may also be affected.

SOLUTION:
Restrict use to trusted servers only.
