tag_insight = "A number of vulnerabilities have been discovered in XFree86:

CVE-2004-0083: Buffer overflow in ReadFontAlias from dirfile.c of
XFree86 4.1.0 through 4.3.0 allows local users and remote attackers to
execute arbitrary code via a font alias file (font.alias) with a long
token, a different vulnerability than CVE-2004-0084.

CVE-2004-0084: Buffer overflow in the ReadFontAlias function in XFree86
4.1.0 to 4.3.0, when using the CopyISOLatin1Lowered function, allows
local or remote authenticated users to execute arbitrary code via a
malformed entry in the font alias (font.alias) file, a different
vulnerability than CVE-2004-0083.

CVE-2004-0106: Miscellaneous additional flaws in XFree86's handling of
font files.

CVE-2003-0690: xdm does not verify whether the pam_setcred function call
succeeds, which may allow attackers to gain root privileges by
triggering error conditions within PAM modules, as demonstrated in
certain configurations of the MIT pam_krb5 module.

CVE-2004-0093, CVE-2004-0094: Denial-of-service attacks against the X
server by clients using the GLX extension and Direct Rendering
Infrastructure are possible due to unchecked client data (out-of-bounds
array indexes [CVE-2004-0093] and integer signedness errors
[CVE-2004-0094]).

Exploitation of CVE-2004-0083, CVE-2004-0084, CVE-2004-0106,
CVE-2004-0093 and CVE-2004-0094 would require a connection to the X
server.  By default, display managers in Debian start the X server
with a configuration which only accepts local connections, but if the
configuration is changed to allow remote connections, or X servers are
started by other means, then these bugs could be exploited remotely.
Since the X server usually runs with root privileges, these bugs could
potentially be exploited to gain root privileges.

No attack vector for CVE-2003-0690 is known at this time.

For the stable distribution (woody) these problems have been fixed in
version 4.1.0-16woody3.

For the unstable distribution (sid) these problems have been fixed in
version 4.3.0-2.

We recommend that you update your xfree86 package.";
