| <description> |
| <p> |
| Damian Put and an anonymous researcher reported a potential heap-based |
| buffer overflow vulnerability in rebuildpe.c responsible for the |
| rebuilding of an unpacked PE file, and a possible crash in chmunpack.c |
| in the CHM unpacker. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| By sending a malicious attachment to a mail server running ClamAV, or |
| providing a malicious file to ClamAV through any other method, a remote |
| attacker could cause a Denial of Service and potentially the execution |
| of arbitrary code with the permissions of the user running ClamAV. |
| </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-0.88.5"</code> |
| </resolution> |
