http://security.gentoo.org/

Severity:	normal
Title:	xine-lib: Buffer overflows
Date:	09/13/2006
Bugs:	#133520
ID:	200609-08

Synopsis

xine-lib is vulnerable to multiple buffer overflows that could be exploited to execute arbitrary code.

Background

xine is a high performance, portable and reusable multimedia playback engine. xine-lib is xine's core engine.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/xine-lib	< 1.1.2-r2	>= 1.1.2-r2	All supported architectures

Description

xine-lib contains buffer overflows in the processing of AVI. Additionally, xine-lib is vulnerable to a buffer overflow in the HTTP plugin (xineplug_inp_http.so) via a long reply from an HTTP server.

Impact

An attacker could trigger the buffer overflow vulnerabilities by enticing a user to load a specially crafted AVI file in xine. This might result in the execution of arbitrary code with the rights of the user running xine. Additionally, a remote HTTP server serving a xine client a specially crafted reply could crash xine and possibly execute arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All xine-lib users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.2-r2"
