Description Ville Skyttä 2007-03-23 17:24:33 EDT
Cloning RHEL bug for FE[56].

+++ This bug was initially created as a clone of Bug #228013 +++

Sven Krewitt of Secunia reported two flaws he discovered in the way XMMS handles
skin files.  Here are the technical details provided by Sven:

--- Details ---

1) An integer underflow error exists when loading skin bitmap images,
which can be exploited to cause a stack-based buffer overflow via
specially crafted skin images containing manipulated header information.

The vulnerability is caused due to errors within "read_bmp()" in
xmms/bmp.c when loading skin bitmap images.

-- xmms/bmp.c --
GdkPixmap *read_bmp(gchar * filename)
fseek(file, 8, SEEK_CUR);
read_le_long(file, &offset); <-- [1]
read_le_long(file, &headSize);
else if (bitcount != 24 && bitcount != 16 && bitcount != 32)
gint ncols, i;

ncols = offset - headSize - 14; <-- [2]
if (headSize == 12)
ncols = MIN(ncols / 3, 256);
for (i = 0; i < ncols; i++)
fread(&rgb_quads[i], 3, 1, file);
ncols = MIN(ncols / 4, 256);
fread(rgb_quads, 4, ncols, file); <-- [3]

"offset" [1] is not properly verified before being used to calculate
"ncols" [2]. "bitcount" has to be set to a different value than 24, 16
or 32 (but can also be user controlled).
This can be exploited to cause a integer underflow,
resulting in a stack based buffer overflow, which can be used to
overwrite the return address of "read_bmp()" [3].

Successful exploitation allows execution of arbitrary code.

2) An integer overflow error exists when loading skin bitmap images.
This can be exploited to cause a memory corruption via specially crafted
skin images containing manipulated header information.

-- xmms/bmp.c --
GdkPixmap *read_bmp(gchar * filename)
else if (headSize == 40) /* BITMAPINFO */
guint16 tmp;

read_le_long(file, &w); <-- [4]
read_le_long(file, &h); <-- [4]
fseek(file, offset, SEEK_SET);
buffer = g_malloc(imgsize);
fread(buffer, imgsize, 1, file);
data = g_malloc0((w * 3 * h) + 3); <-- [5]

if (bitcount == 1)

These flaws also affect RHEL2.1 and RHEL3

-- Additional comment from davidz@redhat.com on 2007-02-09 12:32 EST --
Are there patches for these yet?

-- Additional comment from bressers@redhat.com on 2007-02-09 13:19 EST --
There are no patches yet.  I'm still trying to contact someone upstream about
this.  If you have any upstream contacts, please let me know.

Comment 1 Michael Shigorin 2007-03-25 15:34:18 EDT
havard@xmms I guess, but that way can take quite some time I'm afraid...

Imported in rawhide - will wait to see if it helps for a week and import into
core 08/04/07

Fedora apologizes that these issues have not been resolved yet. We're
sorry it's taken so long for your bug to be properly triaged and acted
on. We appreciate the time you took to report this issue and want to
make sure no important bugs slip through the cracks.

If you're currently running a version of Fedora Core between 1 and 6,
please note that Fedora no longer maintains these releases. We strongly
encourage you to upgrade to a current Fedora release. In order to
refocus our efforts as a project we are flagging all of the open bugs
for releases which are no longer maintained and closing them.

If this bug is still open against Fedora Core 1 through 6, thirty days
from now, it will be closed 'WONTFIX'. If you can reporduce this bug in
the latest Fedora version, please change to the respective version. If
you are unable to do this, please add a comment to this bug requesting
the change.

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

The process we are following is outlined here:

We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.
