| Hanno boeck reported an error in libclamav/chmunpack.c when processing |
| CHM files (CVE-2008-1389). Other unspecified vulnerabilities were also |
| reported, including a NULL pointer dereference in libclamav |
| (CVE-2008-3912), memory leaks in freshclam/manager.c (CVE-2008-3913), |
| and file descriptor leaks in libclamav/others.c and libclamav/sis.c |
| (CVE-2008-3914). |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could entice a user or automated system to scan a |
| specially crafted CHM, possibly resulting in a Denial of Service |
| (daemon crash). The other attack vectors mentioned above could also |
| result in a Denial of Service. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All ClamAV users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.94"</code> |
| </resolution> |
