Description Tomas Hoger 2008-11-04 08:22:46 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2008-4907 to the following vulnerability:

The message parsing feature in Dovecot 1.1.4 and 1.1.5, when using the
FETCH ENVELOPE command in the IMAP client, allows remote attackers to
cause a denial of service (persistent crash) via an email with a
malformed From address, which triggers an assertion error, aka
"invalid message address parsing bug."

The CVE-2008-4907 affects only the version of the Dovecot package, as shipped with Fedora release of 10. Maintainer, please upgrade, to the latest upstream 1.1.6 version.

It's sitting in dist-f10-update-candidate and waiting for rel-eng to retag with dist-f10-final
