| <background> |
| <p>The JasPer Project is an open-source initiative to provide a free |
| software-based reference implementation of the codec specified in the |
| JPEG-2000 Part-1 (jpeg2k) standard. |
| </p> |
| </background> |
| <description> |
| <p>Two vulnerabilities have been found in JasPer:</p> |
| |
| <ul> |
| <li>The jpc_cox_getcompparms function in libjasper/jpc/jpc_cs.c contains |
| an error that could overwrite certain callback pointers, possibly |
| causing a heap-based buffer overflow (CVE-2011-4516). |
| </li> |
| <li>The jpc_crg_getparms function in libjasper/jpc/jpc_cs.c uses an |
| incorrect data type, possibly causing a heap-based buffer overflow |
| (CVE-2011-4517). |
| </li> |
| </ul> |
| </description> |
| <impact type="normal"> |
| <p>A remote attacker could entice a user or automated system to process |
| specially crafted JPEG-2000 files with an application using JasPer, |
| possibly resulting in the execution of arbitrary code with the privileges |
| of the application, or a Denial of Service. |
| </p> |
| </impact> |
| <workaround> |
| <p>There is no known workaround at this time.</p> |
| </workaround> |
| <resolution> |
| <p>All JasPer users should upgrade to the latest version:</p> |
| |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r4" |
| </code> |
