RHEL 3 : samba (RHSA-2004:467)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated samba packages that fix two denial of service vulnerabilities
are now available.

[Updated 23rd September 2004] Packages have been updated to include
the ppc64 packages which were left out of the initial errata.

Samba provides file and printer sharing services to SMB/CIFS clients.

The Samba team has discovered a denial of service bug in the smbd
daemon. A defect in smbd's ASN.1 parsing allows an attacker to send a
specially crafted packet during the authentication request which will
send the newly spawned smbd process into an infinite loop. Given
enough of these packets, it is possible to exhaust the available
memory on the server. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0807 to this issue.

Additionally the Samba team has also discovered a denial of service
bug in the nmbd daemon. It is possible that an attacker could send a
specially crafted UDP packet which could allow the attacker to
anonymously crash nmbd. This issue only affects nmbd daemons which are
configured to process domain logons. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-0808
to this issue.

Users of Samba should upgrade to these updated packages, which contain
an upgrade to Samba-3.0.7, which is not vulnerable to these issues.
