A missing memory allocation failure check flaw, leading to a NULL pointer dereference, was found in the CUPS 'texttops' filter. An attacker could create a malicious text file that would cause 'texttops' to crash or, potentially, execute arbitrary code as the 'lp' user if the file was printed. (CVE-2010-0542)

A Cross-Site Request Forgery (CSRF) issue was found in the CUPS web interface. If a remote attacker could trick a user, who is logged into the CUPS web interface as an administrator, into visiting a specially crafted website, the attacker could reconfigure and disable CUPS, and gain access to print jobs and system files. (CVE-2010-0540)

Note: As a result of the fix for CVE-2010-0540, cookies must now be enabled in your web browser to use the CUPS web interface.

An uninitialized memory read issue was found in the CUPS web interface. If an attacker had access to the CUPS web interface, they could use a specially crafted URL to leverage this flaw to read a limited amount of memory from the cupsd process, possibly obtaining sensitive information. (CVE-2010-1748)

After installing this update, the cupsd daemon will be restarted automatically.

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)

Updated cups packages that fix three security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems. The CUPS 'texttops' filter converts text files to PostScript.

Users of cups are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the cupsd daemon will be restarted automatically.

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)

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.

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.

Multiple vulnerabilities were discovered and corrected in cups :

Cross-site request forgery (CSRF) vulnerability in the web interface in CUPS, allows remote attackers to hijack the authentication of administrators for requests that change settings (CVE-2010-0540).

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-2010-0542).

The web interface in CUPS, reads uninitialized memory during handling of form variables, which allows context-dependent attackers to obtain sensitive information from cupsd process memory via unspecified vectors (CVE-2010-1748).

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-2010-2431).

ipp.c in cupsd in CUPS 1.4.4 and earlier does not properly allocate memory for attribute values with invalid string data types, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly execute arbitrary code via a crafted IPP request (CVE-2010-2941).

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.

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)

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

  - 715643: heap overflow in gif decoder (CVE-2011-3170)     This update also fixes the following non-security issues :

  - 671735: CUPS backends do not clear messages like     'Waiting for printer to finish...'

Adrian Pastor and Tim Starling discovered that the CUPS web interface incorrectly protected against cross-site request forgery (CSRF) attacks. If an authenticated user were tricked into visiting a malicious website while logged into CUPS, a remote attacker could modify the CUPS configuration and possibly steal confidential data.
(CVE-2010-0540)

It was discovered that CUPS did not properly handle memory allocations in the texttops filter. If a user or automated system were tricked into printing a crafted text file, a remote attacker could cause a denial of service or possibly execute arbitrary code with privileges of the CUPS user (lp). (CVE-2010-0542)

Luca Carettoni discovered that the CUPS web interface incorrectly handled form variables. A remote attacker who had access to the CUPS web interface could use this flaw to read a limited amount of memory from the cupsd process and possibly obtain confidential data.
(CVE-2010-1748).
