-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : lftp SUMMARY : Buffer overflow vulnerability DATE : 2004-01-06 09:46:00 ID : CLA-2004:800 RELEVANT RELEASES : 8, 9 - ------------------------------------------------------------------------- DESCRIPTION lftp[1] is a command-line file transfer program which supports many protocols. Ulf Härnhammar reported[2] two buffer overflow vulnerabilities[3] in the lftp program. An attacker could prepare a directory on a server which, if accessed with a vulnerable lftp with the "ls" or "rels" command, could cause arbitrary code to be executed on the client. SOLUTION It is recommended that all lftp users upgrade their packages.
