The vulnerabilities are caused due to boundary errors related to the incorrect use of the "snprintf()" and "vsnprintf()" functions, which can be exploited to cause buffer overflows. The vulnerabilities are reported in versions prior to 4.3.0. Solution Update to version 4.3.0. and from upstream changelog: http://www.spamdyke.org/documentation/Changelog.txt : Fixed a number of very serious errors in the usage of snprintf()/vsnprintf(). The return value was being used as the length of the string printed into the buffer, but the return value really indicates the length of the string that *could* be printed if the buffer were of infinite size. Because the returned value could be larger than the buffer's size, this meant remotely exploitable buffer overflows were possible, depending on spamdyke's configuration. and from upstream mailing list: http://email@example.com/msg00014.html it also fixes a series of major bugs that could lead to buffer overflows. Depending on spamdyke's configuration, these could cause remotely exploitable security holes. Please upgrade immediately!
