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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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:
http://store.mandriva.com/product_info.php?cPath=149&amp;products_id=4 90

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...'

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.

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.

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)

Red Hat would like to thank the Apple Product Security team for responsibly reporting these issues. Upstream acknowledges regenrecht as the original reporter of CVE-2010-0542; Adrian 'pagvac' Pastor of GNUCITIZEN and Tim Starling as the original reporters of CVE-2010-0540; and Luca Carettoni as the original reporter of CVE-2010-1748.

    (CVE-2005-3625)

  - Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others,     allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a     null dereference. (CVE-2005-3626)

  - Stream.cc in Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor,     and others, allows attackers to modify memory and possibly execute arbitrary code via a DCTDecode stream     with (1) a large number of components value that is not checked by DCTStream::readBaselineSOF or     DCTStream::readProgressiveSOF, (2) a large Huffman table index value that is not checked by     DCTStream::readHuffmanTables, and (3) certain uses of the scanInfo.numComps value by     DCTStream::readScanInfo.
