CVE-2011-2721

First published: Tue Jul 26 2011(Updated: )

An off-by-one error was found in the way the hash manager of Clam AntiVirus, a GPL anti-virus toolkit for UNIX, performed scan of messages with certain hashes. A remote attacker could provide a message with specially-crafted hash signature in it, leading to denial of service (clamscan executable crash). Upstream bug report: [1] <a href="https://wwws.clamav.net/bugzilla/show_bug.cgi?id=2818">https://wwws.clamav.net/bugzilla/show_bug.cgi?id=2818</a> Relevant patch: [2] <a href="http://git.clamav.net/gitweb?p=clamav-devel.git;a=commit;h=4842733eb3f09be61caeed83778bb6679141dbc5">http://git.clamav.net/gitweb?p=clamav-devel.git;a=commit;h=4842733eb3f09be61caeed83778bb6679141dbc5</a> Other references: [3] <a href="https://bugzilla.novell.com/show_bug.cgi?id=708263">https://bugzilla.novell.com/show_bug.cgi?id=708263</a> [4] <a href="http://git.clamav.net/gitweb?p=clamav-devel.git;a=blob_plain;f=ChangeLog;hb=clamav-0.97.2">http://git.clamav.net/gitweb?p=clamav-devel.git;a=blob_plain;f=ChangeLog;hb=clamav-0.97.2</a> [5] <a href="http://www.clamav.net/lang/en/">http://www.clamav.net/lang/en/</a>
