"The jpc_qcx_getcompparms function in jpc/jpc_cs.c for the JasPer JPEG-2000
library (libjasper) before 1.900 allows remote user-assisted attackers to cause
a denial of service (crash) and possibly corrupt the heap via malformed image
files, as originally demonstrated using imagemagick convert."
Appears to affect 1.900.1 too.

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

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.

"Niels Provos libevent 1.2 and 1.2a allows remote attackers to cause a denial of

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.

"Several vulnerabilities have been discovered in the QEMU processor emulator,
which may lead to the execution of arbitrary code or denial of service. The
Common Vulnerabilities and Exposures project identifies the following problems:
CVE-2007-1320
Tavis Ormandy discovered that a memory management routine of the Cirrus video
driver performs insufficient bounds checking, which might allow the execution of
arbitrary code through a heap overflow.
CVE-2007-1321
Tavis Ormandy discovered that the NE2000 network driver and the socket code
perform insufficient input validation, which might allow the execution of
arbitrary code through a heap overflow.

Tavis Ormandy discovered that the "icebp" instruction can be abused to terminate
the emulation, resulting in denial of service.
