"A number of vulnerabilities have been discovered in XFree86. The
corrections are listed below with the identification from the Common
Vulnerabilities and Exposures (CVE) project :

  - CAN-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 CAN-2004-0084.

  - CAN-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
    CAN-2004-0083.

  - CAN-2004-0106 :

    Miscellaneous additional flaws in XFree86's handling of
    font files.

  - CAN-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.

  - CAN-2004-0093, CAN-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 [CAN-2004-0093] and integer
    signedness errors [CAN-2004-0094]).

Exploitation of CAN-2004-0083, CAN-2004-0084, CAN-2004-0106,
CAN-2004-0093 and CAN-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 CAN-2003-0690 is known at this time."

"Updated XFree86 packages that fix a privilege escalation vulnerability
are now available.

[Update 16 February 2004] Erratum filelist has been modified for
x86_64 and s390x only so that the correct multi-lib packages are
available.

XFree86 is an implementation of the X Window System, providing the
core graphical user interface and video drivers.

iDefense discovered two buffer overflows in the parsing of the
'font.alias' file. A local attacker could exploit this vulnerability
by creating a carefully-crafted file and gaining root privileges. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CVE-2004-0083 and CVE-2004-0084 to these issues.

Additionally David Dawes discovered additional flaws in reading font
files. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0106 to these issues.

All users of XFree86 are advised to upgrade to these erratum packages,
which contain a backported fix and are not vulnerable to these issues.

Red Hat would like to thank David Dawes from XFree86 for the patches
and notification of these issues."

"Two buffer overflow vulnerabilities were found by iDEFENSE in
XFree86's parsing of the font.alias file. The X server, which runs as
root, fails to check the length of user-provided input; as a result a
malicious user could craft a malformed font.alias file causing a
buffer overflow upon parsing, which could eventually lead to the
execution of arbitrary code.

Additional vulnerabilities were found by David Dawes, also in the
reading of font files.

The updated packages have a patch from David Dawes to correct these
vulnerabilities."
