Komlin <avkvladru at mail.ru> reports few vulnerabilities in El Gamal - based algorithms A weakness found in El Gamal - based algorithms allows to create valid signature without knowledge of private key by introducing minor modifications in document. This problem is known to exist in Russian official GOST 34.19-2001 standard. It's not known if it affects ECDSA. There are also few minor problems mostly connected with unclear border values definitions.

There was also report by DocSoft <docsoft at mail.ru> on buffer overflow in some older version of ncftpd on Solaris , but I was not able to reproduce it at least on demo version of ncftpd >= 2.5.0 under FreeBSD, so it was bounced. Overflow is on FTP DELE command with buffer > 256 bytes. Feel free to contact DocSoft if you can confirm vulnerability. -- http://www.security.nnov.ru /\_/\ { , . } |\ +--oQQo->{ ^ }<-----+ \ | ZARAZA U 3APA3A } +-------------o66o--+ / |/ You know my name - look up my number (The Beatles)
