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 HДrnhammar 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.
