Samba told us on Nov07 that Samba <3.0.8 is vulnerable to a remote
DoS. Public on Nov08 1500 UTC
"A bug in the input validation routines used to match filename strings
containing wildcard characters may allow a user to consume more than
normal amounts of CPU cycles thus impacting the performance and
response of the server."
CAN-2004-0930 Affects: FC2
CAN-2004-0930 Probably Affects: FC3
(samba-3.0.8-0.pre1.3 is included in FC3 which looks vulnerable, needs
Embargoed (but only for a few hours).
Additionally - During a code audit, Stefan Esser discovered a buffer
overflow in Samba versions prior to 3.0.8 when handling unicode
filenames. An authenticated remote user could exploit this bug which
may lead to arbitrary code execution on the server. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CAN-2004-0882 to this issue. Red Hat believes that the
Exec-Shield technology will block attempts to remotely exploit this
vulnerability on x86 architectures. This issue was public on 20041115.
