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.

The remote host is affected by the vulnerability described in GLSA-201207-10 (CUPS: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in CUPS. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker may be able to execute arbitrary code using specially       crafted streams, IPP requests or files, or cause a Denial of Service       (daemon crash or hang). A local attacker may be able to gain escalated       privileges or overwrite arbitrary files. Furthermore, a remote attacker       may be able to obtain sensitive information from the CUPS process or       hijack a CUPS administrator authentication request.
  Workaround :

    There is no known workaround at this time.

This update fixes the following security issues :

  - 601830: CSRF via admin web interface. (CVE-2010-0540)

  - 680210: users in group 'lp' can overwrite arbitrary     files. (CVE-2010-2431)

  - 680212: denial of service via cupsDoAuthentication.
    (CVE-2010-2432)

  - 711490: heap overflow in gif decoder. (CVE-2011-2896)

  - 715643: heap overflow in gif decoder (CVE-2011-3170)

Multiple vulnerabilities has been discovered and corrected in cups :

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 (CVE-2010-2432).

The LZW decompressor in the LWZReadByte function in giftoppm.c in the David Koblas GIF decoder in PBMPLUS, as used in the gif_read_lzw function in filter/image-gif.c in CUPS before 1.4.7, the LZWReadByte function in plug-ins/common/file-gif-load.c in GIMP 2.6.11 and earlier, the LZWReadByte function in img/gifread.c in XPCE in SWI-Prolog 5.10.4 and earlier, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows remote attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2895 (CVE-2011-2896).

The gif_read_lzw function in filter/image-gif.c in CUPS 1.4.8 and earlier does not properly handle the first code word in an LZW stream, which allows remote attackers to trigger a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted stream, a different vulnerability than CVE-2011-2896 (CVE-2011-3170).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

The updated packages have been patched to correct these issues.

Several vulnerabilities have been discovered in the Common UNIX Printing System :

  - CVE-2008-5183     A NULL pointer dereference in RSS job completion     notifications could lead to denial of service.

  - CVE-2009-3553     It was discovered that incorrect file descriptor     handling could lead to denial of service.

  - CVE-2010-0540     A cross-site request forgery vulnerability was     discovered in the web interface.

  - CVE-2010-0542     Incorrect memory management in the filter subsystem     could lead to denial of service.

  - CVE-2010-1748     Information disclosure in the web interface.

  - CVE-2010-2431     Emmanuel Bouillon discovered a symlink vulnerability in     handling of cache files.

  - CVE-2010-2432     Denial of service in the authentication code.

  - CVE-2010-2941     Incorrect memory management in the IPP code could lead     to denial of service or the execution of arbitrary code.

According to its banner, the version of CUPS installed on the remote host is earlier than 1.4.4. Such versions are affected by several vulnerabilities :

  - The patch for STR #3200 / CVE-2009-3553 was not     complete. A remote client can cause a denial of service     by causing the CUPS server to reference an already     freed resource. (STR #3490) (CVE-2010-0302)

  - The CUPS daemon may be vulnerable to certain cross-site     request forgery (CSRF) attacks, e.g., malicious IFRAME     attacks. (STR #3498) (CVE-2010-0540)

  - An unprivileged process may be able to cause the CUPS     server to overwrite arbitrary files as the root user.
    (STR #3510) (CVE-2010-2431)

  - The CUPS daemon is vulnerable to a heap corruption     attack as the 'textops' filter does not verify the     results of memory allocations. It is possible this     may lead to arbitrary code execution. (STR #3516)     (CVE-2010-0542)

  - The CUPS daemon is vulnerable to a denial of service     attack if compiled without HAVE_GSSAPI. (STR #3518)     (CVE-2010-2432)

  - The CUPS daemon is vulnerable to an information     disclosure attack as an attacker can view portions of     uninitialized memory by a specially crafted URL.
    (STR #3577) (CVE-2010-1748)

The remote host is running CUPS, an open source print server. 

Versions of CUPS earlier than 1.4.4 are potentially affected by multiple vulnerabilities.

  - The texttops filter does not check the results of memory allocations. (STR #3715)

  - A use-after-free vulnerability in the abstract file-descriptor handling interface.  Note that this is related to an incomplete patch for CVE-2009-3553. (STR #3490)

  - In certain instances, the web interface can disclose the contents of memory. (STR #3577)

  - CUPS can overwrite files as root in directories not owned or writeable by non-root users. (STR #3510)

  - An infinite loop can occur when CUPS is not compiled with HAVE_GSSAPI. (STR #3518)
