Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been discovered in CUPS, allowing for the |
| 19 |
remote execution of arbitrary code and a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
CUPS provides a portable printing layer for UNIX-based operating |
| 25 |
systems. |
| 26 |
|
| 27 |
Affected packages |
| 28 |

Package / Vulnerable / Unaffected |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities have been reported in CUPS: |
| 39 |
|
| 40 |
* regenrecht (VeriSign iDefense) discovered that the |
| 41 |
cgiCompileSearch() function used in several CGI scripts in CUPS' |
| 42 |
administration interface does not correctly calculate boundaries when |
| 43 |
processing a user-provided regular expression, leading to a |
| 44 |
heap-based buffer overflow (CVE-2008-0047). |
| 45 |
|
| 46 |
* Helge Blischke reported a double free() vulnerability in the |
| 47 |
process_browse_data() function when adding or removing remote shared |
| 48 |
printers (CVE-2008-0882). |
| 49 |
|
| 50 |
* Tomas Hoger (Red Hat) reported that the gif_read_lzw() function |
| 51 |
uses the code_size value from GIF images without properly checking |
| 52 |
it, leading to a buffer overflow (CVE-2008-1373). |
| 53 |
|
| 54 |
* An unspecified input validation error was discovered in the HP-GL/2 |
| 55 |
filter (CVE-2008-0053). |

Impact |
| 58 |
====== |
| 59 |
|
| 60 |
A local attacker could send specially crafted network packets or print |
| 61 |
jobs and possibly execute arbitrary code with the privileges of the |
| 62 |
user running CUPS (usually lp), or cause a Denial of Service. The |
| 63 |
vulnerabilities are exploitable via the network when CUPS is sharing |
| 64 |
printers remotely. |
| 65 |
|
| 66 |
Workaround |
| 67 |
========== |
| 68 |
|
| 69 |
There is no known workaround at this time. |
| 70 |
|
| 71 |
Resolution |
| 72 |
========== |
| 73 |
|
| 74 |
All CUPS users should upgrade to the latest version: |
| 75 |
|
| 76 |
# emerge --sync |
| 77 |
# emerge --ask --oneshot --verbose ">=net-print/cups-1.2.12-r7" |
| 78 |
