  Severity: 3
      Type: Remote

Summary
======
Multiple vulnerabilities have been fixed in cups.


Description
==========
CVE-2010-0540:

Cross-site request forgery (CSRF) vulnerability in the web interface in
CUPS before 1.4.4, as used on Apple Mac OS X  10.5.8,  Mac  OS  X  10.6
before 10.6.4, and other platforms, allows remote attackers  to  hijack
the authentication of administrators for requests that change settings.



CVE-2010-0542:

The _WriteProlog function in texttops.c in texttops in the Text  Filter
subsystem in CUPS before 1.4.4 does not  check  the  return  values  of
certain calloc calls, which allows remote attackers to cause a denial of
service (NULL pointer dereference or heap memory corruption) or possibly
execute arbitrary code via a crafted file.



CVE-2010-1748:

The cgi_initialize_string function in cgi-bin/var.c in the web interface
in CUPS before 1.4.4, as used on Apple Mac OS X 10.5.8, Mac OS  X  10.6
before 10.6.4, and other platforms, does not properly handle  parameter
values containing a % (percent) character without  two  subsequent  hex
characters, which allows context-dependent attackers to obtain sensitive
information  from cupsd  process  memory  via  a  crafted  request,  as
demonstated   by the    (1)    /admin?OP=redirect&URL=%    and    (2)
/admin?URL=/admin/&OP=% URIs.



CVE-2010-2431:

The cupsFileOpen function in CUPS before 1.4.4 allows local users, with
lp group membership, to overwrite arbitrary files via a symlink  attack
on the (1) /var/cache/cups/remote.cache or (2) /var/cache/cups/job.cache
file.



CVE-2010-2432:

The cupsDoAuthentication function in auth.c in the client in CUPS before
1.4.4, when HAVE_GSSAPI is omitted, does not properly handle  a  demand
for authorization, which allows remote CUPS servers to cause a denial of
service (infinite loop) via HTTP_UNAUTHORIZED responses.


Affected packages:

  Pardus 2009:
    cups, all before 1.3.11-67-11
