CVE-2011-2896

TITLE

CUPS Used in products such as LZW Infinite loop vulnerability in decompressor

DESCRIPTION

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. The problem is CVE-2006-1168 and CVE-2011-2895 May be related toA third party could be put into an infinite loop and execute arbitrary code through a crafted compressed stream. GIMP is prone to a buffer-overflow vulnerability Successfully exploiting this issue may allow attackers to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. The software enables a variety of image manipulations, including photo retouching, image compositing, and image creation. Description: The GIMP (GNU Image Manipulation Program) is an image composition and editing program. Bugs fixed (http://bugzilla.redhat.com/): 727800 - CVE-2011-2896 David Koblas' GIF decoder LZW decoder buffer overflow 839020 - CVE-2012-3403 gimp (CEL plug-in): heap buffer overflow when loading external palette files 847303 - CVE-2012-3481 Gimp (GIF plug-in): Heap-based buffer overflow by loading certain GIF images 6. (CVE-2011-2896) This update also fixes the following bugs: * Prior to this update, the "Show Completed Jobs," "Show All Jobs," and "Show Active Jobs" buttons returned results globally across all printers and not the results for the specified printer. With this update, jobs from only the selected printer are shown. (BZ#625900) * Prior to this update, the code of the serial backend contained a wrong condition. As a consequence, print jobs on the raw print queue could not be canceled. This update modifies the condition in the serial backend code. Now, the user can cancel these print jobs. (BZ#625955) * Prior to this update, the textonly filter did not work if used as a pipe, for example when the command line did not specify the filename and the number of copies was always 1. This update modifies the condition in the textonly filter. Now, the data are sent to the printer regardless of the number of copies specified. (BZ#660518) * Prior to this update, the file descriptor count increased until it ran out of resources when the cups daemon was running with enabled Security-Enhanced Linux (SELinux) features. With this update, all resources are allocated only once. (BZ#668009) * Prior to this update, CUPS incorrectly handled the en_US.ASCII value for the LANG environment variable. This update fixes the handling of the en_US.ASCII value and the binaries now write to standard output properly. Bugs fixed (http://bugzilla.redhat.com/): 625900 - STR #3436: Jobs buttons not working correctly when viewing a specific printer 625955 - Serial back end has inverted SIGTERM block 660518 - textonly filter won't work as a pipe with copies=1 668009 - avc calls leak file descriptors 727800 - CVE-2011-2896 David Koblas' GIF decoder LZW decoder buffer overflow 6.

Summary: Updated cups packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems. A heap-based buffer overflow flaw was found in the Lempel-Ziv-Welch (LZW) decompression algorithm implementation used by the CUPS GIF image format reader. An attacker could create a malicious GIF image file that, when printed, could possibly cause CUPS to crash or, potentially, execute arbitrary code with the privileges of the "lp" user. (CVE-2011-2896) These updated cups packages also provide fixes for the following bugs: * Previously CUPS was not correctly handling the language setting LANG=en_US.ASCII. As a consequence lpadmin, lpstat and lpinfo binaries were not displaying any output when the LANG=en_US.ASCII environment variable was used. As a result of this update the problem is fixed and the expected output is now displayed. (BZ#681836) * Previously the scheduler did not check for empty values of several configuration directives. As a consequence it was possible for the CUPS daemon (cupsd) to crash when a configuration file contained certain empty values. With this update the problem is fixed and cupsd no longer crashes when reading such a configuration file. (BZ#706673) * Previously when printing to a raw print queue, when using certain printer models, CUPS was incorrectly sending SNMP queries. As a consequence there was a noticeable 4-second delay between queueing the job and the start of printing. With this update the problem is fixed and CUPS no longer tries to collect SNMP supply and status information for raw print queues. (BZ#709896) * Previously when using the BrowsePoll directive it could happen that the CUPS printer polling daemon (cups-polld) began polling before the network interfaces were set up after a system boot. CUPS was then caching the failed hostname lookup. As a consequence no printers were found and the error, "Host name lookup failure", was logged. With this update the code that re-initializes the resolver after failure in cups-polld is fixed and as a result CUPS will obtain the correct network settings to use in printer discovery. (BZ#712430) * The MaxJobs directive controls the maximum number of print jobs that are kept in memory. Previously, once the number of jobs reached the limit, the CUPS system failed to automatically purge the data file associated with the oldest completed job from the system in order to make room for a new print job. This bug has been fixed, and the jobs beyond the set limit are now properly purged. (BZ#735505) * The cups init script (/etc/rc.d/init.d/cups) uses the daemon function (from /etc/rc.d/init.d/functions) to start the cups process, but previously it did not source a configuration file from the /etc/sysconfig/ directory. As a consequence, it was difficult to cleanly set the nice level or cgroup for the cups daemon by setting the NICELEVEL or CGROUP_DAEMON variables. With this update, the init script is fixed. (BZ#744791) All users of CUPS are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. After installing this update, the cupsd daemon will be restarted automatically. 4.
