(CUPS: Multiple vulnerabilities)

    Multiple vulnerabilities have been reported in CUPS:
    regenrecht (VeriSign iDefense) discovered that the
    cgiCompileSearch() function used in several CGI scripts in CUPS'
    administration interface does not correctly calculate boundaries when
    processing a user-provided regular expression, leading to a heap-based
    buffer overflow (CVE-2008-0047).
    Helge Blischke reported a
    double free() vulnerability in the process_browse_data() function when
    adding or removing remote shared printers (CVE-2008-0882).
    Tomas Hoger (Red Hat) reported that the gif_read_lzw() function
    uses the code_size value from GIF images without properly checking it,
    leading to a buffer overflow (CVE-2008-1373).
    An unspecified
    input validation error was discovered in the HP-GL/2 filter
    (CVE-2008-0053).
  
Impact :

    A local attacker could send specially crafted network packets or print
    jobs and possibly execute arbitrary code with the privileges of the
    user running CUPS (usually lp), or cause a Denial of Service. The
    vulnerabilities are exploitable via the network when CUPS is sharing
    printers remotely.
  
Workaround :

    There is no known workaround at this time."

"From Red Hat Security Advisory 2008:0192 :

Updated cups packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The Common UNIX Printing System (CUPS) provides a portable printing
layer for UNIX(R) operating systems.

A heap buffer overflow flaw was found in a CUPS administration
interface CGI script. A local attacker able to connect to the IPP port
(TCP port 631) could send a malicious request causing the script to
crash or, potentially, execute arbitrary code as the 'lp' user. Please
note: the default CUPS configuration in Red Hat Enterprise Linux 5
does not allow remote connections to the IPP TCP port. (CVE-2008-0047)

Red Hat would like to thank 'regenrecht' for reporting this issue.

This issue did not affect the versions of CUPS as shipped with Red Hat
Enterprise Linux 3 or 4.

Two overflows were discovered in the HP-GL/2-to-PostScript filter. An
attacker could create a malicious HP-GL/2 file that could possibly
execute arbitrary code as the 'lp' user if the file is printed.
(CVE-2008-0053)

A buffer overflow flaw was discovered in the GIF decoding routines
used by CUPS image converting filters 'imagetops' and 'imagetoraster'.
An attacker could create a malicious GIF file that could possibly
execute arbitrary code as the 'lp' user if the file was printed.
(CVE-2008-1373)

All cups users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues."
