Greetings, I am requesting a CVE ID for the issue described below. Thanks. Best regards Matthias Andree bogofilter-SA-2010-01 Topic: heap corruption overrun in bogofilter/bogolexer Announcement: bogofilter-SA-2010-01 Writer: Matthias Andree Version: 0.1 CVE ID: Announced: Category: vulnerability Type: array index underflow/out of bounds write through invalid input Impact: heap corruption, application crash Credits: Julius Plenz Danger: medium URL: http://bogofilter.sourceforge.net/security/bogofilter-SA-2010-01 Affected: bogofilter <= 1.2.1 SVN before 2010-07-03 08:40 UTC Not affected: bogofilter 1.2.2 (to be released) 1. Background ============= Bogofilter is a software package for classifying a message as spam or non-spam. It uses a data base to store words and must be trained which messages are spam and non-spam. It uses the probabilities of individual words for classifying the message. Note that the bogofilter project is issuing security announcements only for current "stable" releases, and not necessarily for past "stable" releases. 2. Problem description ====================== Bogofilter's/bogolexer's base64 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. 3. Impact ========= Vulnerable bogofilter and bogolexer applications can corrupt their heap and crash. The consequences are dependent on the local configuration, memory layout and operating system features. 4. Solution =========== Upgrade your bogofilter to version 1.2.2 (or a newer release). bogofilter is available from SourceForge: <https://sourceforge.net/project/showfiles.php?group_id=62265> A.
