Summary: CVE-2007-0653 XMMS multiple issues (CVE-2007-0654)
Product: Fedora Extras
Version: fc6
Platform: All
OS/Version: Linux
Status: NEW
Severity: low
Priority: normal
Component: xmms
AssignedTo: paul(a)all-the-johnsons.co.uk

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 ---
CVE-2007-0654
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);
}
else
{
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.
CVE-2007-0653
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);
fclose(file);
data = g_malloc0((w * 3 * h) + 3); <-- [5]
if (bitcount == 1)

These flaws also affect RHEL2.1 and RHEL3
-- Additional comment from davidz(a)redhat.com on 2007-02-09 12:32 EST --
Are there patches for these yet?
-- Additional comment from bressers(a)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.

Summary: CVE-2007-1030: libevent < 1.3 DoS
Product: Fedora Extras
Version: devel
Platform: All
OS/Version: Linux
Status: NEW
Severity: medium
Priority: normal
Component: libevent

http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-1030
"Niels Provos libevent 1.2 and 1.2a allows remote attackers to cause a denial of
service (infinite loop) via a DNS response containing a label pointer that
references its own offset."
FE5 and FC6 are at 1.1a, not clear if those versions are affected. Rawhide was
updated to 1.2a a few days ago, however (unlike the changelog says) the latest
upstream is 1.3a, not 1.2a.

Summary: CVE-2007-1246: xine-lib buffer overflow
Product: Fedora Extras
Version: fc5
Platform: All
OS/Version: Linux
Status: NEW
Severity: normal
Priority: normal
Component: xine-lib
AssignedTo: gauret(a)free.fr
ReportedBy: ville.skytta(a)iki.fi

CC: fedora-security-list@redhat.com,ville.skytta(a)iki.fi
http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-1246
Originally reported against MPlayer, but it turns out xine-lib is vulnerable
too. Upstream fix pushed to FC6+ (1.1.4-3 currently building), but FC5 is still
at 1.1.2, probably already lacking "several bug and security fixes" as put by
upstream in the 1.1.3 release announcement. No FC5 system here to test with, so
leaving up to Aurelien to decide whether to update while at it or just to
possibly apply the patch for this issue from FC6+ (if it applies, unchecked).
