Description Vincent Danen 2010-07-05 15:01:40 UTC
A flaw was found in bogofilter's/bogolexer's base64 where it could overwrite memory before its heap buffer, if the base64 input started with an equals sign, such as through misdeclaration of quoted-printable as base64.  This would cause bogofilter/bogolexer to corrupt their heap and crash upon receiving such an email message.

Something is wrong with the bogofilter home page, the original referenced advisory [1] is currently unavailable, however a copy in svn [2] is.  This will also be corrected in upstream version 1.2.2; a patch [3] is available.  Please note that upstream version 1.2.2 is not yet available.

This affects bogofilter as shipped in Fedora 12 and 13, as well as EPEL5.
