TITLE:
XMMS Integer Overflow and Underflow Vulnerabilities

SECUNIA ADVISORY ID:
SA23986

VERIFY ADVISORY:
http://secunia.com/advisories/23986/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
XMMS 1.x
http://secunia.com/product/13712/

DESCRIPTION:
Secunia Research has discovered two vulnerabilities in XMMS, which
can be exploited by malicious people to compromise a user's system.

1) An integer underflow error exists in the processing of skin bitmap
images. This can be exploited to cause a stack-based buffer overflow
via specially crafted skin images containing manipulated header
information.

Successful exploitation allows execution of arbitrary code.

2) An integer overflow error exists in the processing of skin bitmap
images. This can be exploited to cause memory corruption via
specially crafted skin images containing manipulated header
information.

Successful exploitation may allow the execution of arbitrary code.

The vulnerabilities are confirmed in version 1.2.10 (Linux). Other
versions may also be affected.

SOLUTION:
Do not install skins from untrusted sources.
