Hello Raphael,
I have an issue with this Glsa (wich is a really usefull service
between, thx) :
I think the affected syscall is xitk_window_dialog_error rather at line
128,231,357 in /src/xitk/errors.c
the "bad" thing is that errors_create_window exists but wasn't modified
at all...
see below...
$ diff ./xine-ui-0.99.4/src/xitk/errors.c
../../xine-ui-0.99.5_pre20060716/work/xine-ui-0.99.5_pre20060716/src/xitk/errors.c

Title: xine-ui: Format string vulnerabilities
Date: January 23, 2007
Bugs: #161558
ID: 200701-18
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
xine-ui improperly handles format strings, possibly allowing for the
execution of arbitrary code.
Background
==========
xine-ui is a skin-based user interface for xine. xine is a free
multimedia player. It plays CDs, DVDs, and VCDs, and can also decode
other common multimedia formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 xine-ui < 0.99.5_pre20060716 >= 0.99.5_pre20060716
Description
===========
Due to the improper handling and use of format strings, the
errors_create_window() function in errors.c does not safely write data
to memory.
Impact
======
An attacker could entice a user to open a specially crafted media file
with xine-ui, and possibly execute arbitrary code.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All xine-ui users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=media-video/xine-ui-0.99.5_pre20060716"
References
==========
