- -------------------------------------------------------------------------- Debian Security Advisory DSA 449-1 [e-mail:security@debian.org] http://www.debian.org/security/ Martin Schulze February 24th, 2004 http://www.debian.org/security/faq - --------------------------------------------------------------------------

Package : metamail Vulnerability : buffer overflow, format string bugs Problem-Type : remote Debian-specific: no CVE ID : CAN-2004-0104 CAN-2004-0105

Ulf Härnhammar discovered two format string bugs (CAN-2004-0104) and two buffer overflow bugs (CAN-2004-0105) in metamail, an implementation of MIME. An attacker could create a carefully-crafted mail message which will execute arbitrary code as the victim when it is opened and parsed through metamail.

We have been devoting some effort to trying to avoid shipping metamail in the future. It became unmaintainable and these are probably not the last of the vulnerabilities.

For the stable distribution (woody) these problems have been fixed in version 2.7-45woody.2.

For the unstable distribution (sid) these problems will be fixed in version 2.7-45.2.

We recommend that you upgrade your metamail package.

Upgrade Instructions - --------------------

wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
