Full Text Bug Listing

- Details -

When parsing the header of an invalid CUE image file or an invalid RealText 
subtitle file, stack-based buffer overflows might occur. 


- Impact -

If successful, a malicious third party could trigger execution of arbitrary 
code within the context of the VLC media player. 


- Threat mitigation -

Exploitation of this issue requires the user to explicitly open a specially 
crafted file.

Arches, please test and mark stable
=media-video/vlc-0.9.6

Target keywords:
amd64 ppc ppc64 sparc x86

This probably depends on bug 245793 being fixed (unable to reproduce here due
to lack of a stable system).

alpha: You need to rekeyword AND stable.
ppc64: Apparently you never had VLC stable, so feel free to un-cc yourself.

Sparc stable, works for me, but of course an exhaustive test of this package is
almost impossible.  Note, for sparc, this carries along a requirement to mark
stable several other packages:
===============
media-video/dirac-1.0.0
media-libs/libkate-0.2.5
media-libs/zvbi-0.2.33
media-libs/schroedinger-1.0.5
media-libs/libass-0.9.5
===========================
Of these, libkate, zvbi, and libass need to be marked stable on everything.

There's a regression. Video is detached from the interface, which was fixed in
media-video/vlc-0.9.4-r1 with the patch 'embeddedvideo.patch', but it was
removed later.

The patch can be applied cleanly to 0.9.6 and works.

The regression was to patch it in order to make it available again...
See bug #240714, my last comment there and the link I posted.

amd64/x86 need the following packages stable, is this ok and which versions
should we pick?

I'll keep vlc ~ppc64 for now.

0.9.8a is stable for ppc
