Red Hat Product Errata RHSA-2004:632 0 high SHIPPED_LIVE Important: samba security update 2004-11-16 05:00:00 UTC

Description Mark J. Cox 2004-11-08 09:24:52 UTC
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: RHEL3

Embargoed (but only for a few hours).

Proposed patch from Samba

Comment 3 Mark J. Cox 2004-11-08 12:30:48 UTC
I'll set this as impact "moderate" as it requires an authenticated
samba user to cause the DoS.

Comment 4 Josh Bressers 2004-11-16 15:58:48 UTC
This issue does appear to affect RHEL2.1 after all.
