| LittleCMS, or short lcms, is a color management system for working with |
| ICC profiles. It is used by many applications including GIMP and |
| Firefox. |

| <description> |
| <p> |
| RedHat reported a null-pointer dereference flaw while processing |
| monochrome ICC profiles (CVE-2009-0793). |
| </p> |
| <p> |
| Chris Evans of Google discovered the following vulnerabilities: |
| </p> |
| <ul> |
| <li>LittleCMS contains severe memory leaks (CVE-2009-0581).</li> |
| <li>LittleCMS is prone to multiple integer overflows, leading to a |
| heap-based buffer overflow (CVE-2009-0723).</li> |
| <li>The |
| ReadSetOfCurves() function is vulnerable to stack-based buffer |
| overflows when called from code paths without a bounds check on channel |
| counts (CVE-2009-0733).</li> |
| </ul> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could entice a user or automated system to open a |
| specially crafted file containing a malicious ICC profile, possibly |
| resulting in the execution of arbitrary code with the privileges of the |
| user running the application or memory exhaustion, leading to a Denial |
| of Service condition. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All LittleCMS users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=media-libs/lcms-1.18-r1"</code> |
| </resolution> |
