Description Tomas Hoger 2009-09-17 07:24:52 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2009-3235 to the following vulnerability:

Multiple stack-based buffer overflows in the Sieve plugin in Dovecot
1.0 before 1.0.4 and 1.1 before 1.1.7, as derived from Cyrus libsieve,
allow context-dependent attackers to cause a denial of service (crash)
and possibly execute arbitrary code via a crafted SIEVE script, as
demonstrated by forwarding an e-mail message to a large number of
recipients, a different vulnerability than CVE-2009-2632.

Note: Sieve implementation used in cyrus-imapd is affected by these issues too.

Cyrus upstream patches:

Comment 1 Tomas Hoger 2009-09-17 07:32:03 UTC
Dovecot update for Fedora 10 already includes these fixes:


Dovecot on Fedora 11+ (uses different sieve plugin) and Red Hat Enterprise Linux 4 and 5 (no sieve plugin) are not affected by his flaw.

cyrus-imapd packages in Fedora and Red Hat Enterprise Linux will be updated to address this flaws.

Comment 3 Tomas Hoger 2009-09-17 07:52:14 UTC
Mitigation notes:

All these additional overflows are sprintf()s to static char buffers.  On Red Hat Enterprise Linux 5 and later (including all current Fedora versoins), these overflows are caught by FORTIFY_SOURCE reducing the impact to controlled abort of one of the cyrus-imapd child processes that are later re-spawned by the master.

Comment 4 Fedora Update System 2009-09-18 14:40:56 UTC
cyrus-imapd-2.3.15-1.fc10 has been submitted as an update for Fedora 10.

Comment 5 Fedora Update System 2009-09-18 14:41:03 UTC
cyrus-imapd-2.3.15-1.fc11 has been submitted as an update for Fedora 11.

Comment 7 errata-xmlrpc 2009-09-23 14:55:42 UTC
This issue has been addressed in following products:

  Red Hat Enterprise Linux 5
  Red Hat Enterprise Linux 4
