Full Text Bug Listing

Secunia:

Luigi Auriemma has reported some vulnerabilities in xine-lib, which
potentially can be exploited by malicious people to compromise a
user's system.

The vulnerabilities are caused due to integer overflow errors when
allocating memory in src/demuxers/demux_flv.c,
src/demuxers/demux_qt.c, src/demuxers/demux_real.c,
src/demuxers/demux_wc3movie.c, src/demuxers/ebml.c, and
src/demuxers/demux_film.c. These can be exploited to cause heap-based
buffer overflows via overly large fields included in e.g. FLV, MOV,
RM, MVE, MKV, and CAK files.

The vulnerabilities are reported in version 1.1.11. Other versions
may also be affected.

SOLUTION:
Do not open untrusted files using xine-lib.

PROVIDED AND/OR DISCOVERED BY:
Luigi Auriemma

ORIGINAL ADVISORY:
http://aluigi.altervista.org/adv/xinehof-adv.txt

flameeyes, are these fixed upstream?

These were not known to upstream until now, and it's now freakin' easter, don't
expect me to find a way to fix them before tuesday... incidentally I decided to
use easter as timeframe to clean up my office's cabling -_-;

FWIW, they should _all_ be fixed in 1.2 series, I suppose backporting the
relevant changes, if possible, would solve the issue. 1.2 makes good use of
calloc rather than using malloc directly.

Diego, is there any update here?

Upstream is handling it as bug 71:
http://bugs.xine-project.org/show_bug.cgi?id=71
There is a patch but I wasn't able to doublecheck its commit status yet, sorry
I'm behind with my own schedule.

Merged here:
http://hg.debian.org/hg/xine-lib/xine-lib?cmd=changeset;node=a3f2772fd14b;style=gitweb
http://hg.debian.org/hg/xine-lib/xine-lib?cmd=changeset;node=08bb2b5bfddd;style=gitweb

Although it seems this here is worth merging too:

ping, flamy and others?

Ok, I should have checked before. Fixes released as 1.1.11.1 (omg!). Please
bump.

bumped; there was two (known to me) regressions in this release, they're
patched.
