| <p> |
| Clam AntiVirus (short: ClamAV) is an anti-virus toolkit for UNIX, |
| designed especially for e-mail scanning on mail gateways. |
| </p> |
| </background> |
| <description> |
| <p> |
| Multiple vulnerabilities have been found in ClamAV: |
| </p> |
| <ul> |
| <li>The |
| vendor reported a Divide-by-zero error in the PE ("Portable |
| Executable"; Windows .exe) file handling of ClamAV |
| (CVE-2008-6680).</li> |
| <li>Jeffrey Thomas Peckham found a flaw in |
| libclamav/untar.c, possibly resulting in an infinite loop when |
| processing TAR archives in clamd and clamscan (CVE-2009-1270).</li> |
| <li>Martin Olsen reported a vulnerability in the CLI_ISCONTAINED macro |
| in libclamav/others.h, when processing UPack archives |
| (CVE-2009-1371).</li> |
| <li>Nigel disclosed a stack-based buffer overflow |
| in the "cli_url_canon()" function in libclamav/phishcheck.c when |
| processing URLs (CVE-2009-1372).</li> |
| </ul> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could entice a user or automated system to process a |
| specially crafted UPack archive or a file containing a specially |
| crafted URL, possibly resulting in the remote execution of arbitrary |
| code with the privileges of the user running the application, or a |
| Denial of Service. Furthermore, a remote attacker could cause a Denial |
| of Service by supplying a specially crafted TAR archive or PE |
| executable to a Clam AntiVirus instance. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Clam AntiVirus users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.95.2"</code> |
